Nice wing display with a sharp face and great water BG. There seems to be a cluster of hot pixels in the chest area, it could be from p/p (misuse of Curves) and easy to recoup. Love the pearly wings.
Nice action image, Stuart. I agree about the hot area on the chest. The background contrasts well with the bird. While most of the bird is quite sharp, I find that the softness in the top wing tends to draw my eye there. I might be tempted to crop a bit from the right side. :)
