Wonderful color in the reflections. Kind of neat how the water above the break is nearly the same color as the bird. Good catch! Best of luck to you in the challenge.
A centered crop is not appealing to me and it looks like you've increased the red way too much. I can't imagine his feet are really that color. The focus is very, very nice though.
Wow - look at those red legs. That's the first thing that jumped out at me about your image. It's a very bright and slightly overly saturated for my personal tastes. I do like the sharpness of the bird though.
