The only thing that disturbs me is the relative size of head and body and the total lack of neck on the mock-up character. Although it can be common in caricatures, it gives the feeling that you picked some existing game's character silouhetto and just stick your character's head over it.
^tried an edit: essentially made the character wider and shortened its legs a little bit so that he now looks like squashed/dwarvish (Rick Dangerous style) rather than deformed.
