I don't know about likeness, as I don't know what Virginia Wolf looked like, but what you have going though it looks good, seems to suffer from the facial characteristics being disproportionate and placed strangely. The thing about the forehead, you didn't really adress it as much as you could have from your first post to your last, dunno if the edit is useful for that, as I said, it comes down to likeness and boy, are real human faces sometimes very 'unrealistic', but from a point of view of good facial construction, I tweaked stuff.
Also, the way the nose and eyes are placed seems to suggest an angle that the mouth and chin do not follow, if you can see what I mean. I tried to adress this in my edit but I didn't do it well enough.
