I think the main issues have been covered pretty well here. Mixing the two types of lighting has really thrown the WB off, the DOF is pretty thin, and the pose is really not that flattering.
Derrel mentioned it shows a lot of cleavage. Personally, I'd go further than that and say:
1. I'm not a big fan of chopping off a photo in the middle of a person's bosom, any more than chopping off their fingers or toes. It's awkward looking.
2. Admittedly, my vision isn't great. But either there is a shadow being cast on her right breast that kinda LOOKS like her nipple, or her cleavage is so exposed it's actually showing her nipple. Maybe that very slightly NSFW look is what you were going for, but I don't get the impression that it is--I get more of an impression that you just didn't notice how that looks.
I also find the raised arm and chopped-off elbow in the background distracting. And that eyelash thing, but that's already been covered.
Get her to look just a little more toward the camera, fix the mixed-lighting issue, and work on posing. But hey, you DID get a nice catchlight in her eye!
