C&C per req:
1. Main issue here is the angle; whether you like angles or not is purely a personal taste, but when you have something that is supposed to be vertical and isn't (the tree) it impinges on the overall image. As well, the lighting is a bit harsh; perhaps a diffuser to reduce the bright area around her lower torso?
2. Not bad; the skin tone is a bit warm, and she appears slightly over-exposed. How often are you shooting a white-card?
3. Again, slightly warm looking skin, and a preponderance of vertical elements; I think this image needs more area to the right; what is she looking at?
4. Nice casual pose, but again, harsh lighting image left, and shadow image right. I'm not sure that I like the way her feet are positioned with her right not being visible, and her left partly hidden.
5. A classic pose, and well executed; needs leveling, and and again harsh lighting, but not too bad.
Overall, nice images; two main issues are leveling and exposure. These look like they shot too close to mid-day; ideally, 8-9.00am would be the time for best light
Good work, keep at it.
Just my $00.02 worth - your milage may vary.
