When Hairless. Men and Women share many of the same features. The main difference is in the nose, cheek bones, and the jaw line. Females usually have a narrower, “cuter” nose, if a supermodel type, then higher more pronounced cheek bones. and a narrower more rounded jaw line. where as a “mans” man would have a broad nose, wider instead of higher cheek bones, to match a wider, more angular jaw. And a lot of this depends on the “build” of the character you are making. if your modeling a not-so-muscular/manly man, then the face would be pretty much the same as a female. Same difference as if you were modeling a muscular warrior woman, her features would be a bit closer to a man (especially if she used steroids in her back story).
Lots of stuff to consider, but the moral of the story is. theirs not THAT much difference between a man and a woman. you will probably find that the hair will define the gender as much as any other part of the anatomy. The lips on your character scream woman to me. as well as the eyes. Was she modeled off an Asian reference photo?
The main thing that makes her look male. is the divot down the middle of her chin. try rounding that out and she will look like a whole different person!
edit: also just noticed the indentation on the bridge of her nose. plump that out a bit so its not making a shadow there. Key is to avoid hard lines for a woman, and gently encourage them for a man.
