Nice, unique image. The water is still enough for a perfect shot, but the ripples keep the whole thing interesting and provides the needed movement in the image to keep the viewers attention. Good collection of shapes and angles with the rocks which really give the photo some nice definition.
If I were to make any negative comment at all, it would be the (simply cannot be helped) lack of color variation. I think if there was (for example) a couple more rocks popping above the water surface it would have given a way to help draw the viewer's eyes into your image. Although I don't think it detracts from your work in anway.
I love it, keep up the excellent work.
p.s. I only did the negative part, because I read that you were supposed to do that in the Caedes "how to post a good comment" section. I'm not really qualified by any stretch of the imagination to critique anything or anybody. So, please don't be offended. The picture is great and I have it in my current run of rotating desktop images.
