John,
I like the image, I think it will benefit from noise reduction on the background, burning the reflection on the legs and tight crop. I also notice something strange around the beak.
I include a repost let me know what you think.
Nice light showing under wing detail. Stands out well against the dark BG. Lots of colour and luminance noise in the BG- what ISO was this shot at? Very strange effect around the feet and bill - give the impression of on camera flash casting a shadow on the BG behind the bird which should not be the case with a distant dark sky. Raul's repost has cleaned up the noise well.
