If previous advice on her hands has confused you, then keep this in mind: A hand should be able to cover half of the face, length- and width-wise. Gimme a few and I'll see if I can't whip up a quick redline for ya, oki-doke? :3
Edit: Here's the redline I promised. I'm no expert with humanoids, but I love drawing hands. xD I'm weird...
Anyway, I hope this helps illustrate my point. Hands are generally about the same length, wrist-to-tip-of-middle-finger, as the face, from chin-to-hairline or roundabouts.
