He is too fat. Several pieces of outlining have been skipped on the jacket and i think too much black has been used.
I do however like the overall idea for the sprite. Good work.
Boredom project, like I said. And my intentions were to make him look ridiculous (tiny head, enourmous body). So thanks for being honest, but I think it's fine, since I wasn't trying.
Also, thanks for repeating the same thing after someone (and more) already said it. Really makes my day! /sarcasm
