The sprite that you use now is too short, or at least his head and torso are too wide in comparison to your body height. You may want to either make him thinner, or make him taller. I suggest taller, because not only is he shorter than the girl sprite, but because making him thinner would suggest revamping the whole head part.
EDIT: I'll make a new sprite for you if you still want one. That old one I offered you first I decided I'm going to use for a sprite comic.
