Another interestingly different approach. as with a couple of similar shots, my first reaction is that I might like them as a wallpaper - which in itself tells you what I find wrong with it as a challnge entry - there just is't a point which holds the interest, that arrests the eye. I do very much like the tonality, and that use of light as a means of transmitting the idea of a ruffled surface of water, however.
I likw this image a lot. The composition is good because the larger rocks in the foreground and center of the image provide a focal point that keeps my eye in the photo. The highlights provide an interesting pattern. It is a tranquilizing image. Good job.
