Oh I liked this one during the challenge and I would have thought it would have scored higher. What cracked me up was that it looked like the one bird was mooning the other and the white duck was just like "wha?" Too bad it's bill wasn't open too. Great catch of the action!
Looks like the humor route paid off, Rob - a pretty respectable score. :) The white gal does seem to have an air of alarm about her, like, "oh, my lord, he just showed me his ASS!"
Well, bottoms up. Nice catch. Good colors and contrast and not over-saturated. Focus is good. Catchlight in the eyes is missing, this can be done with fill flash and that would have helped ballance the light with this shot. As it is the whites are a bit blown out.
