I don't think is right write comments with one or two words to great arts. I know is hard make art, some time the time don't let we do that, sometime the laziness make we get on the front of TV all the day. This is why I'm writing big comments, you don't exactly need to write feedbacks, but read already is a way to say "thank you".
Sorry for that thing up there, I don't know why I write that...
Is a simple boy with a cool hair, but I love how you simply put simple details in an amazing way. But your re-work was, sincerelly, one of the best I've seen. Not because it is perfect, because it is expressive. The combination of lines (like these one close to eyes and on the short) that you used was great.
It can sound weird, but the arm irregularity is the best part of the drawing. Yeah, is weird because rarelly a good artist will put a anatomy error. But the arm irregularity with your style combines. They look irregular, as the "arm flexors" did not existed. But the difference is what give life to cartoons. New things make new worlds.
And I can deduce where is his spine, he looks a little derp that way, but this makes the drawing even better. I don't understand very much of art, you know better, I'm pretty sure. But based on what do I learn about art with the time I can say you're better than the animators of the Cartoon Network.
