Looking good so far, here is a couple items that of course are different from person to person and proportions are differently for everybody, but eyes are usualy around half way up the skullm hers seem higher, but the final could have more hair on top and fix that, just mentioning it. Mouth angle and perspective seem off from the rest of face.
It looks good, I am just trying to help out, hope I didn't insult the girl of your dreams!
