Love how the water looks like glass here and how the heron is dragging his foot causing the water spray. Those things add quite a bit of interest to a photograph that would otherwise not be as special b/c of a not so terrific light angle. I really like this capture and the different perspective it offers.
What I like most about this image is the vegetation in the near right third of the image. Great wing action in the heron while its head appears much too streamlined and a little overexposed. Tough shot while trying to get the underwings lighter. The splash is very well done with a nice reflection in the water.
