Great shot, but it feels a bit soft in the stones, which should be crips and sharp to contrast the smoothness of everything else, in my humble opinion. :D Lovely.

I really like the idea behind the picture, and the thumbnail actually had a lot of impact. I think that the impact is diminished by image quality. I also think that the picture would have more impact if you didn't have the reflections at the top of the shot, just the stones and the water/sky.

From the thumbnail this looked great, at full size I'm disappointed! It looks like it's either not focussed properly or softened by jpeg compression / resizing. So nearly!
