* If you have back face culling enabled, you can see through her throat. Even if you disable it, there's still something that looks odd on her throat * If you open her jaw, the shape of her lower lips seems weird, like there's some sort of a weight issue but there isn't. It can be worked to make it look decent but it's tricky. * Her chin is a bit sharp, the cheeks need to be a bit more puffy too. * Eyelashes move a bit weird, especially when you're moving her eyebrows.
I checked the rest of the body and things seem to move just fine. The head is probably what you need to look at more. BTW I just included the cosmetic stuff just in case you did a bit of sculpting on her.
Have to say though, this is really good. Can't wait for all those Underworld mods.
