You have a gorgeous model here! Just a couple of things I noticed...
1. I would have had the fan blowing her hair the opposite direction, kept it out of her face for this shot.
2. It's an ok shot, I probably would have had the model tilt her head down into the frame more. Just having the bottom of her head is distracting to me.
3. Doesn't do anything for me. I would clone out the light reflection in her glasses.
4. The best of the lot and my favorite as well! 
5. I really like this one as well, nice and clean good conversion
6. She's a gorgeous young lady, I would have tightened up on here a little on this one.
7. Nice pose, I would have scooted her a little more forward so that the bottom hem of her skirt was showing under her legs, plus that way you don't get the dreaded thigh bulge!
8. Nice shot, I love the look she has here.
Overall, your lighting is terrific; no hotspots and very even. I would love to see more!
