I’m surprised you haven’t had more responses. I agree you’ll have to post wire to get geometry feedback. We need more angles as well.
All I could really say from this would be to maybe take in the creases on the sides of the nose a bit more. Shape of the eyes is a little strange, perhaps add some more variation so that the eyelids actually look like they’re wrapping around a sphere not so smooth all the way across, looks like they’re being pulled on the sides; that’s kinda what makes her look surprised.
This is a pretty good piece so far. The texture is looking nice although obviously a bit symmetrical 
I’d prefer a little thicker eyebrows, just my opinion.
