I love the lighting and colours on this. Everything seems to be in harmony from the soft BG pallet, to the interesting rock perch, to the feather patterns on the plover. The open beak also make the shot. I can almost hear him. The low angle of view really simplifies this image. Nicely done.
What a fine image!!! It's crisp, the color palette is awesome and I love that calling pose. While you could go tighter, I am liking the space you have given the plover!
