I decided to play around with an alternate Tricolored Heron image to see what I could come up with. For this one I have adjusted the composition without cropping and use a variety of quick masks and clone stamp to tidy up the imperfect reflection. I will try to post the original image in a reply immediately following this post.
Nikon D200
80-400 VR lens @ 400mm (effective = 600mm) (VR on - handheld)
ISO 200
f8 @ 1./250 sec.
You managed to do quite well with the PP. I think it's pretty appealing as the end result. The improvement if possible would be to get a little lower, but then you'd have more BG clutter perhaps with that muddy bank? Keep 'em coming mate. :)
