the hairbands around the wrist drive me crazy in photos.
It depends on what type of look you're going for.
I'd probably whiten/brighten the teeth, clone out the hair band, clone out the indentation from where the hair band was, clone out the little black dots on the inside of her hand, soften up the bags under her right eye (and maybe a touch around the left eye), even out the nail polish on her ring finger, dodge up her face just a touch, and burn down her shirt just a touch, eyes need major sharpening.
As far as thing that probably can't be fixed very well, that could have been done better in the camera: the flowers could probably stand to be more out of focus. They're kind of oddly dark looking and they mostly distract from the subject. I think her fingers are kind of awkwardly close to her mouth (but maybe that's just me). Picture seems just a tad bit blurry. Was this purely natural light? Seems like a softbox a ways away from her upper left (camera upper right), powered down a bit could have helped a lot with the lighting.
