Hi Ahmed. I'm 64 and have done all sorts of art education (Famous Artists, art college, etc.) in my life and am a working artist. This is a note to say that I greatly appreciate you as a teacher. You practice what you preach and what you preach is right. I love the structure that is so evident in your course and your no-nonsense, relaxed delivery. I hope you have continued success! And kudos to Proko for being a great source of art education.
