I have considered making tutorials and exercises about drawing. That's why I'm asking: would you want me to do some? Even though I'm drawing in japanese manga-style (if you can call that even a style), the methods I use are applicable basically in any field of art.
Art has a lot of liberties, but I believe there are many rules that should be followed. I mean, there certainly are valid reasons why some drawings look better than others. Thus you can't simply ignore issues by saying "it's my style" or "I took artistic liberties". I don't perceive myself as an artist, I'm simply following certain rules to achieve the look I seek. That said, you don't have to be artistically talented to become good at drawing. These rules can be learnt by anyone. The more realistic look you aim for, the more stricter the rules are.
That said, I didn't born with polished skills. It's been all thanks to vigorous practice and love towards manga (also naivety at the beginning). I've been drawing around 10 years, and it took me 6 years to understand that I don't know anything about drawing. Now I'm at point where I can say that I know a little at least.
I can't teach you how to draw. But I can help you learn how to see. Seeing is fundamental part of drawing. Many people draw things the way they think they look, not the way they really are.
I believe in honesty, so if someone asks me what I think about their drawings, I say what I really think. I may like it, but it automatically doesn't mean it's a successful drawing (and vice versa). My personal opinions and artistic views might contradict each other a lot. However, I can't give in depth critiques to everybody. I have few "apprentices" and they are my priority. I'll compile common issues within tutorials if I decide to make them.
Note: the examples are all drawn by me. It took some effort to do things horribly wrong.
