A striking image of a beautiful bird. I don't mind the sand-covered bill since it shows what he's been up (or down) to. I do wish we could see his feet, although the oof base does give it an ethereal feel. Light and background are lovely.
Awesome colours, nice warmth and richness to them. Great low angle too. The "cloudy" layer covering the feet looks good to me and makes the hidden feet tolerable....but I like Dan's suggestion of adding some below, if you have it (and then top and left only to retain the original balance and ratio). The one thing hurting the image, IMO, is the head angle which would have been perfect turned towards us a few degrees more.
I have a soft spot for these type of images where the bird appears to come out of a 'dreamy' foreground, so this appeals to me. Lovely lighting on the bird as well.
Beautiful shot normally I would say shame the feet are missing but in this instance you can guess there is a sandbar in the way so that makes it ok in my eyes!
