C&C per req:
1. High contrast, under-exposed and not fond of the angle. Additionally some fill light subject left would have helped.
2. As per #1
3. Ummm... nice branches?
4. This one has potential; I quite like the overall idea, and the bright sky behind works. It needs a re-shoot in a slightly different location without the cars. Because of the sky, the image itself is at least 2/3 stop under-exposed. Be careful to avoid cropping little bits of things (her foot) out.
5. Good exposure and expression in this one; perhaps a bit too tightly cropped on her face. As well, the background really detracts from the image.
6. A little too much contrast, and really don't like the expression.
7. Nice expression, good pose, but not such a good location and you've cropped too close to the front.
8. Cropped fingers on her right hand, slightly over-exposed, and the expression; looks like she's going to slap you.
9. Nice conversion, just a bit under-exposed (~ 1/2 stop), but really don't like the angle.
Overall, some nice work, and creative thinking with a few minor technical issues. The comments on poses and expressions are purely subjective; if they work for you and her, that's what counts.
Just my $00.02 worth - your milage may vary.
