Hi Michael - Not such a good day for the Iguana - like the action and the wingspread.
The whites in the areas without the shadows are pushing the envelope a little, you can probably recover them via a multiply layer in P.S - The issue here being some of your subject is in shadow whilst other parts are in bright sunlight - mixed light is tough - Plus you have a black and white subject, Soft light is the real key to these guys - to get detail in the blacks and not blow out the whites.
As presented I would add a touch of contrast - looks just a tad flat.
Hi Michael,
I like the capture and flight angle...would suggest a little boost in the contrast and toning down the warm whites in the head...looking forward to your next one...:cool:
