HELP!!

[Soujrnr]

So there I was at a group shoot. i got to photograph this incredibly beautiful young lady (and I screwed up the shot really bad as you will be able to tell immediately). Be that as it may, notice how the shade of her face is DIFFERENT than the shade of her body. She was a very tan lady but the MUA made her face different than the rest of her body. Don't ask why because I have no ****ing idea what she was thinking. And so, I want to know how I can touch up her face to make it match the rest of her body. Can someone post some detailed instructions on how I can do this?

Thanks.

Here's the photo.
