In this art I really like the shapes for their solidity, the colors for their vivacity, the lines for their confidence and the character pose/framing for its dynamism; the whole thing is also full of personality, I'd say, and I also like that.
My only concern is that some details on top of the forearms and legs seem to me to blur a little the other strong aspects of the drawing, namely the lines and shapes, or at least distract me a little from them, so I'd suggest IMO to try to harmonize them all better.
The whole thing's still awesome, however.
