Exposure isn't bad; just a tad hot, but nothing you couldn't easily dial down in LR. I'm not fond of the pose however; it seems rather inappropriate for a child of this age. I don't mean that in a prudish way, just that, IMO, it doesn't really fit.
I think the exposure looks pretty good. I might try pull her away from the wall a bit so the reflector doesn't light it so much. Would give more separation. Just a thought...
