I'm not quite sure it looks feminine enough, right now it could be a man. Then again that's just my opinion, and also probably the lack of hair. It definitely looks like a solid piece though as far as proportions and shaping go.
Looks pretty good, of course a face is one of those things that its hard to say unless you have it fully to look at and see what looks wrong. Like hair, eyes, ears, right now I don't see anything immediately wrong.
