I used a spot light and adjusted it so that her face is lit, and I am running a render right now. I'll post when it's complete.

EDIT: the spot light was originally inside the wall, but behind the mirror, so the mirror was blocking it. Moving her back and then moving the spotlight to the other side of the mirror did the trick.

I am going to play with the spotlight scale after I finish this render. I want to see if I can just light her face and not the neck and shoulders area which I have now.

If I had a nickle for ever time a woman told me to get lost, I could buy Manhattan.
