C&C per req:
1. A case of extremes; very dark shadow, with excess highlights on the face. While it's not always necessary to have the subject stare right into the lens, it's generally good to have them looking toward the camera.
2. Nice composition and expsoure, however I think this woudl benefit from a closer crop to bring more attention to the subject. If you are going to leave it as-is, I'd recommend cloning out the bit of clothing image left.
3. A nice subject, but the harsh flat light doesn't work very well. I'd suggest shooting this one either earlier or later in the day; a circular polarizer would help. Additionally, a longer shutter-speed (2 sec+ ) to soften the water might work.
