Too much green.... You can even see green teeth! If you notice, either the tweaking of the colors or maybe extreme cropping has caused a LOT of "pixelation" in the shot. :( You always "pay" for extreme adjustments in unwanted side-effects.
here's my take on it. Used channel mixer to make the colours a little more natural (IMO, anyway), the neat image to clean it up. Bumped the contrast a bit, and upped the gamma to brighten a few of his features.
no offense messin' with your image...you did ask :)
I was told, I cant remember by who... that when taking pics of animals, it's always best to get down to the same level as the animal... But I like ur shot, but I cant say that the dolphin's mouth is the prettiest av seen ;)
When I was little I always thought of dolphins as cute toothless vegetarians lol...
