actually, her face looks pretty easy to get to from V4.  the general shape you could probably get by dialing Morphs++.  it looks like her nose would be the hardest part of her face.

my suggestion is that you find a profile and a 3/4ths view.  the 3/4ths helps more than you might think. 

what would be really interesting is if you actually worked on her body, too.  individuality isn't all in the head, you know ;D.
