I think it's great. It reminds me of the cover of Surface Magazine's "Soft Geometry" issue.
I think a slightly looser crop would really improve this shot. As well I think the perspective would be improved by rotating the model just slightly so his head is closer to the camera, and to shoot from a slightly lower angle in order to better see both of his arms. I suggest a lower angle because I think it would compliment the diving concept by making it seem like we the viewer are looking up toward the diver, as most do when watching someone take a dive.
