Harsh, eh? Okay, here goes:
-The AAing on the top of his head makes no sense, and actually makes it look jaggier than if it wasn't there. In fact, the AAing on this piece in general could use some work.
-The Selout used on the hand is really bad, and doesn't really make sense. Why use selout on the inside of a sprite?
It seems dragonrc beat me to the punch (...). His edit is a step in the right direction.
