riflessi

It's quite interesting how the smooth, green water suddenly breaks into the rounded, multi-colored patterns; it's a very nice capture.  You might check the levelness; from the shoreline and the trees, it appears to be sloping down to the right.  Another composition to consider would be a tighter shot with just a portion of the green water and the riffles you have here -- that would even be somewhat of an abstract shot.

Nice to see your larger thumbnails and images -- makes it much easier to see what you've captured.
