The reflections in the rippling water, and the glistening, shimmering light is so beautiful. The high-key effect works nicely with the high-contrst. Neat shot!
While I definitely see high contrast here, I'm not sure it does the image any good, as it seems to be boosted by post processing methods (I realize this is an assumption). I think the subject is good, the boy's facial expression adds drama to the photograph and the composition is very nice with him in the right foreground. There is an odd sheen to his skin that makes the image look just a little bit faded and plastic, and I wish the focus was a tad sharper around his face. I gave a 5.
The photographer kept some texture in the water which really adds to the whole mood. There is good definition between the boy and the water even though they are almost the same tone. I would have given this one of my highest scores if the boy had a little less motion.
