Nice.

There's a wee bit of Werner Klocke about it, which isn't bad if you like Werner Klocke's female faces. But since this is a new WIP I have few hesitations about throwing my weight around.

For
my own tastes, I'd smooth the brow down a bit and push that spare mass to the top of the head. (Be sure about
where the eyeline goes.

) By the same token, maybe flatten the sides of the whole 'teardrop' a bit, and push it down to the jaw. Just a bit.
One of the bigger problems I had with the previous face was the slight 'sausage lips' effect. (Although like I said, there was a lot of glare in the video) If you want to accentuate them this time, raise them in the middle, but gradually blend them down and in towards the corners. Also, for the lower lip, try pushing in a little more under the lip, rather than adding much more mass on top of it. (See the linked pic again)
Also, don't be afraid to add more slopes and dips and wings to the nose. It might seem counterintuitive for 'smooth' female faces, but if you don't go overboard it should look fine when you step back from it. And if you do go overboard, it's easily pushed back again.

Last thing: what are your references?
