C&C:
This looks like a potentially really nice group of images which are almost, but not quite there.
1,2: Both give the appearance [to me] of someone who is cramped and uncomfortable; she does not look happy. The highlights on her left side are somewhat distracting. I think a diffuser over the rear window of the car would have helped.
3. Starkly contrasting shadows and highlights, and esp. the blown highlights behind her are issues. As well, I'm not fond of the expression; she appears to expecting something to fall on her.
4. Extreme issues with highlights and shadows in this one, but the pos is nicer.
5. Nice pose, at least one stop under in her face/chest area, still suffereing with the highlights behind her, and a colour-caste issue. Did you change your WB?
6. The composition of this one doesn't work; the long lines of the wall on the left take your eye right past the subject and out of the image; this could solved with a crop. Her hair could be lighter by at least a half-stop.
7, 8. Nice composition, but the exposure/WB in these two aren't qutie right.
9. The pose in this is very awkward. She seems very uncomfortable, particularily with the positioning of her left leg.
The main issue from my perspective, is one of exposure. I am guessing that you took these images using just your camera? Unfortunately, the bright sun wasn't your friend. Diffusers, reflectors and fill light would have made some of these images killer!
Just my $00.02 worth - your milage may vary!
