The first thing that I notice is an inconsistency in the texture of the skin in the face and above the forward eye as well as around the hair line.
You could create a new layer and then use a soft brush in color mode to paint in a unified tone. Then reduce the opacity into the 20-30% depending on the color you choose. The only issue here is, you'll risk flattening the contrast on the face.
What method are you using for resurfacing her skin? Do you employ a gaussian blur at all?
