This one has a double highlight in her eyes. I'd remove the lower one (in each eye) using photoshop. I might even move the upper one to a slightly higher position. If you shoot this shot again, I might try to move my upper flash a little higher to put the highlight in the one o'clock position on the pupil.
She doesn't pop out of the background as much on this shot as she does on most others. I might try to shoot this one with a lower exposure on the background and a little more on her. Personally, I'd also go to a less conspicuous shoe although I realize that you weren't looking for that kind of feedback from this thread.
I'd like to see a version of this one with the front flash a little higher. I'm not certain that the shot would be better, but maybe the result would be better. I love the backlighting on this one. You did that part just right.
