Not a bad first attempt at all; of course there's always room for improvement. A few thoughts per req:
1. The skin is just a tad hot on this one. A drop in exposure by 1/3 stop would have nailed it I think. Also, watch things like the little curl of "unattached" hair by her necklace.
2. Don't get it... Yes, she has nice legs, but....
3. This would be nice IF it was just a little wider; the cropped garment image right bothers me, and I'm not really fond of the treatment. It looks like old Kodak Gold developed at a 1hr mall stand using old chemicals.
4. Too little DoF; her whole face should be in focus, and her expression doesn't really say, "Come hither, more like, "Have you finished mowing the lawn yet?"
5. What's the main point of focus supposed to be? I would say it should be her breasts, but again, DoF works agains you. Also, the hotspot just above her ear should have been dealt with.
6. A little more breast and a little more DoF, as well as all of her hair would have helped.
My main thoughts are: Use a smaller aperture for more DoF, watch the details (hair, etc), and make sure the client's expressions match the image.
Just my $00.02 worth - your mileage may vary.
