The reason for your drawing looking so crappy is that you have the basic anatomy wrong; your shading and coloring actually looks somewhat decent to me. Males tend to be more square-shouldered and block-like in form (which is how your character appears), while females are more rounded in form and tend to have breasts rather than being flat-chested (definitely not in your picture). I drew an approximation of your character the way I would have drawn her (This was drawn entirely with a computer mouse, so hence the crappy lines+shapes and simplistic shading).
Compare that to your drawing, and it becomes clear which appears more feminine, although I still don't understand the whole flat-on-top bald head idea for a female character.
