I'mso used to seeing sprites with ramrod straight posture that it took me a minute to understand that he was standing at an angle. It seems sort of crooked at first.
I think you have something pretty nice here so far. Maybe you could refine it so that the midsection (knees to just below chest) of the guy is a little more clearly defined. It seems kind of random/blobby.
Not bad at all; the only thing I would change is his left leg (viewer's right). It's a little bent; it looks malformed.
Nice, I really liked the color decisions.
