To do away with the facial highlights on a new layer margued an area and filled it with close to wanted flesh tone and then switched it to multiple setting and fine tuned darkness w/Brightness and contrast, and then softened with gaussian blur then tweaked again with percentage of OP and fill.
Here is my 15 minute try. I just adjusted the color levels, adjusted the color in the eyes, lips and water and then used the healing brush in some places....
A little bit of straightening (ha! seeing it now, looks like I missed the mark a little bit there), some color adjustments, tried fixing the hot spot on her nose, a little blur thrown in to bring more attention to the faces... I'm no Photoshop master, but enjoyed getting a little practice with your picture
