Looking good Dj!
As said the ears definitely need re-evaluating, and you might want to make the Brow bone slightly more prominent, and also bring in the eyelid a bit at the top. At the moment she looks Asian. Which isn't a problem.... It just doesn't look anything like Natalie Portman
Also maybe the Sterno Mastoids should be slightly more prominent.... But thats probably being too picky.
Anyway, nice work thus far!
