I really like the proximity and perfect focus that allows picking up the fine, hair-like feather detail here. This guy? is a beauty. The white, feather-like ripples on the water add a nice touch to the image too.
Nice exposure, color, sharpness and composition. The diagonal perch is good, and so is the background. If it were mine though, I'd consider removing the plant on the left side of the frame, because it catches my eye. But despite that minor personal preference, this is a fine image as is.
An unusual view of a great looking heron. Love the IQ of the entire frame especially the rich detail and very nice perch. Like patterns created in the water. The only thing I might suggest is a bit more room, if you have, on both sides.
