Reckon you've got a lovely model there, grumpy, You've brought out a great smile and she looks very relaxed.
Just a couple of constructives I hope... 1 needs to be pin sharp on the eyes and it just misses the sweet focus. Also, most of them would, I think, benefit from some softer light... particularly 3 with the sharply defined shadow from the on camera flash, some diffusion or bounce would help but taking it off camera would be even better if possible.
