A good character. I feel you should add a bit more 'character' to the hands. A few knuckle bumps here and there would do the trick

Check out the character of Ego in the wall paper section. Look at the thumb in particular, perhaps a mild version of these type of hands. I would also make the feet/shoes bigger (not too much though) and give them some more shape, more visual interest, not necessarily clown sized shoes but something along those lines. It will also help balance him out a bit more because of the larger head.

Just some thoughts for you to either chew on or spit back at me LOL

cheers
