The color is a little weird. Her expression isn't very complimentary. The shadow under her nose looks like ... something. Her makeup (not your fault, I know) isn't helping.
I'm not a portrait photographer so take it for what it is, but that's my take.
yikes didn't even notice the thingy under her nose just a shadow.....but I sometimes hate playing around with shadows for fear my light begins to look flat. The tone is a bit different - darker - , not my usual tones.....was trying for a little bit of an urban feel.....
