First of all, Tina has AWESOME eyes. I feel like I'm falling into a trance if I look at them too long.
In photo #1, I think F/9 is a bit too small of an aperture. I think a shallower depth of field would have done wonders for this photo. Looks like you shot this with a 50mm--so I'm sure you had plenty of room to open the aperture. Composition is nice, except that half of her head is missing.

The best of the three you posted. It is very nicely done. Those EYES!! Once again, shallower depth of field would have worked a little better.
Photo #3:
I hate to say it, but it doesn't do a whole lot for me. I mean, Tina is very pretty and I like looking at topless women as much as the next guy, but, I dunno. I'll let others who are more qualified than me critique it. I think it's the lighting, but I really don't know for sure.
On another note, I've seen lots of your work on here and it is very good, so I'm sure I'm not telling you anything you don't know already. I'm sure your next batch will be off the charts. :cheers:
