I find the colour quite unappealing and flat.
Also, the positioning and arrangement of the rocks are not to my taste - there is no form of thought that appears to be present, though I could be mistaken, I admit. But to me, it just seems like they're being placed there for the sake of there being rocks - I've done it before, of course. =D
Tranquility is there, evident from the calmness of the water due to the apparent long exposure I see, but not drama. I was there the other day as well, and the rays.. Are not quite brought out here in this picture, which would have rendered it a lot more dramatic and improved it quite a bit.
Perhaps, sacrifice the details in the rocks (after finding a more aesthetically pleasing silhouette arrangement), and expose for the rays to be caught? =)
