Hehe that is so bad-ass, it really has some character to this little sprite.
I like it, and it seems to be in style so I don't have any crits.
Oh one thing is his jacket on right, where it goes three pixels in, that area generally looks a little odd, but I can understand working with small pixels is hard so I'm not entirely sure how to fix that up. Some else may have a little more help for you, sorry!
