It's good
It's awesome overall but the problem is he looks like a girl. Firstly, don't make him look too cute and give him a boyish posture or teenage posture... err.. moving on.
More importantly make him look cool and awesome(I'm not saying your drawing isn't cool). Don't make the eyes look too cute so it won't make him look girlish. Overall I think it's really good(Except that he looks like a girl, no offense)
Keep it up on drawing! -thumbs up-
P.S. Sorry if my review is all wrong but I think it's just right
