dang that's an awesome sculpt. i think you nailed her eyes and nose perfectly. the mouth area is a little off imho. she has that pouty lip look where you see some teeth most of the time. really awesome sculpt man. congrats!
The tilted side view and the profile shots look almost perfect. Judging by the frontal pic, it seems like the eyes may be a bit too far apart. That may be whats throwing it off some. It could just be the angle of that photo though, I know it's hard to judge alot of sculpts from photos.
