I was concentrating on a brightly lit rookery in south Louisiana when a flock of black-bellied whistling ducks flew overhead. I started to just ditch the photos because I wasn't able to get much detail in the ducks because of the lighting but I rather like this one. What do you think?
Like the wing position and the sharpness looks good.
The duck looks too dark for me, I would open it up even if the BG goes white. If you want to keep some color in the sky you can lighten the duck with a quick mask or layer mask. Not sure if this is straight or a crop but cropping some would look better also.
