C&C per req:
1. About 1/3 stop over-exposed; you've lost most of the detail on the jacket on her left side.
2. Good exposure in this one, but I'd suggest burning in the ground a little; it's slightly over birght. Also watch your composition; you've cropped off the tip of her elbow. It's fine to crop body parts, but do it boldly so that it looks intentional, and not at/through joints so that it seems accidental.
Both 1 and 2 would be nice pictures if you could see her face; as is, they really do nothing for me.
3. Very nice; the only thing you could do here would be to burn in her face just slightly, other than that, good job.
4. Nicely composed, but the a bit mid-tone rich for my taste. I'd suggest a a bit of a contrast boost and possibly a levels/curves tweak to bring out more black and white.
5. The mono conversion is more pleasing on this one, but I don't like the pose as much. The downcast eye works in #4, but is too exreme in #5.
Just my $00.02 worth - your mileage may vary.
