Trusted teacher: Are you looking to improve your drawing skills or you don't even know where to start but you dream of an art career? Or perhaps you have entrance exams coming up for art school or architecture studies and you want to ensure you will pass? This is an individual course design depending on your request and your starting level. Each course includes lessons filled with instruction information, practice time and homework assignment. You can begin with Level 1 and continue further or choose to start on a specific level. Level 1 - This course is an absolute beginner level. You can hold a pencil and a brush but the starting is so stressful and confusing. You're scared of making a mistake, you don't know where to begin, you're getting lost when it comes to composition or shading whenever you start to draw. I GOT YOU! Those are very common feelings when you start to draw and it can be discouraging, give you a feeling of being stuck or just very dissatisfied with your art. In this course I will guide you through basic traditional art techniques such as pencil sketching, pen and ink drawing, watercolor, and acrylic painting. We will be studying composition, forms, shapes, structure and texture of different objects such as fabric, furniture, animal fur, plants etc. I’ll show you how to achieve depth in your shading, how to understand light, and the effect of fragility of plants or hardship and reflection of metal. I’ll teach you observation, things to look for in the drawing, but most of all I'll give you tools for future independent learning that will save you tons of time while figuring on your own! The key to success is your motivation and time you will dedicate to your homework practice. Level 2 - This course is directed towards people who have some basic understanding of traditional art media techniques such as pencil sketching, pen and ink drawing, watercolor, and acrylic painting. Your art is currently your hobby, but you would like to change it into a career? Know more about art as a business model, get insights into career tips and opportunities. Or do you want to improve your sketching skills, learn to digitise your work, create digital illustrations in Procreate, or combine it all in your own unique way? Level 3 - Advanced. It will focus on your specific desire as an artist and adjust to your skills and technique preferences. During the first introduction skills, I’ll provide some exercises to see how you work and together we will find the way we can work and improve.

Trusted teacher: Hello you wonderful person! :-) If you would like to learn to understand and appreciate yourself better, I hereby offer you the opportunity to walk part of your path of self-knowledge and self-discovery with me as your mentor and companion. How? With mental training and personality development techniques. I like to look behind a person's facade because there is so much to discover! ✨ Let’s create a-ha moments together and help you blossom! Regardless of whether you have ADHD/ADD, social phobia or are highly sensitive (HSP), or simply don't fully understand why you sometimes - for example - react so ambivalently... I would like to work with you individually so that together we can discover your great sides and bring them to light, so that you too can live your true self and thus rest in your center and be more satisfied with yourself. Note: To ensure quality, I do not offer this program as a single lesson, but as a booking package of at least 5 sessions. I look forward to your inquiry so that I can start developing your potential. :-) ⚠️ Note: My native language is German. This offer is aimed at German-speaking people - although I am aware that this ad will be automatically translated into English. ⚠️ PS: By the way, I am LGBTQAI+ friendly and a non-smoker ______________________________________________________________________________________________________ It starts with you When you are not with yourself and decide for yourself, others will not be able to learn from you, how to love you. They will follow you and neglect you, if you neglect yourself. They will despise you, as you despise yourself. You will assume that their opinion is also yours, because you don't say yours. They will ask you little, but tell you a lot. They will expect you that you join in, laugh along, vote along and do not ask, challenge or deny. They will treat you like this, how you treat yourself. But if you value yourself, if you take your inner life seriously, if you listen to yourself and doesn’t let anyone do anything to you, then others will learn to respect you, to honor and love. It starts with you. Ulrich Schaffer (*17 December 1942 in Pomerania), writer and photographer

Justyna - Vienna, Austria60€
Trusted teacher: I graduated from the University of Athens where I attended courses in pedagogics, psychology, and linguistics. I worked at a language center between 2009-2016 where I was a director of studies and taught mainly English as a foreign/second language. Since 2005, when I first started teaching English, I have taught children and adults on a variety of language proficiency levels and with a variety of needs (general knowledge/terminology/for specific purposes), both individually and in groups. I constantly seek progress, meaning that I study further through reading books/articles concerning didactics/methodology and learning difficulties (chiefly dyslexia), observing other teachers as well as attending seminars (online or face-to-face). I will help you learn weird English spelling and pronunciation with fun. I assign homework and after I receive it, correct it thoroughly additionally providing a lot of remarks/examples if they are necessary. During my lessons I use : - Skype/Whatsapp/Messenger to connect with you, - Google Docs to keep notes, which you can check at any time and they are yours to keep, - sketch board me to make mind maps to show connections between ideas, etc. - books, PPP, word docs, diagrams, pics, etc. - pronunciation/spelling/grammar games, - authentic materials were taken from websites. I adore my profession and desire each and every one of my students be satisfied with the lesson. That's why I make sure the atmosphere is stress-free and nice. I also want my lessons to be as effective and close to real-life needs as possible. Therefore, I make sure they are well-prepared, although they can be altered at any point, should such an opportunity arise. I like explaining things in a variety of ways as well as make use of dictionaries, diagrams, etc. When it comes to students who want to obtain certificates, I am very demanding. What can I teach? - I would love to help you improve/develop all language skills (speaking/writing-listening/reading + grammar/vocabulary/pronunciation), - I would love to help you prepare for certificates such as KET / PET / FCE / CAE / CPE / IELTS / TOEFL - I would love to help you prepare for university exams (linguistics / phonetics / history).

Justyna is a graduate of the University of Athens and she is very much qualified to deliver Greek courses. She has great teaching skills and more than 10 years of experience in teaching the Greek language. Her communication skills are also commendable, and she can find the appropriate way to establish a very effective communication with the pupil. She is very meticulous and attentive to detail and she speaks always in a positive tone. The quality of her work is impeccable, and she has also elaborated here own teaching material (for example, PowerPoint presentations) to facilitate the on-line courses. I was very much surprised to see that even the Greek sounds of letters in her PowerPoint file were created with her own voice! With regard to the online courses, she has also the right technical skills to use the various online tools and software (e.g. Google tools), something which is not evident when working with other teachers. She is very flexible in terms of the time of the courses and she is accepting the various time constraints which may derive from the day-to-day schedule of the pupil. She is always in time for her courses and very accessible as well as reliable concerning all the necessary arrangements. In terms of attitude, she is very enthusiastic, an element which has a great impact on the pupil to actively follow up her during the whole duration of the course. She is also very dynamic in the way she delivers the courses, and she does not forget to praise the pupil when necessary. She is always assertive, independently of the learning pace of the pupil. Last but not least, I think she has the right ratio of humour in her courses in order to make the one hour passing with her as pleasant as possible. I highly recommend her from my experience so far.

Japanese lesson by native Japanese speaker (EN / NL) (Lier)
Azuki

rating green star
Very friendly and patient teacher. She explains very well and also tells about Japanese culture. During the lesson we write everything down together so that you can always look back at the things you have learnt. She also does a great job at using material from previous lessons so you don't forget and also get a good feeling of progression. The lessons also have a lot of variety and are very interactive. Most important of all though is that the lessons themselves are very fun! Definitely recommend!

Ignazio is a patient and friendly teacher who's clearly passionate about playing the guitar and sharing his craft with others. The classes are structured and clear. You'll get the right information and the techniques are corrected from the beginning, so you won't need to unlearn some things later.
