Like others said, the composition is spectacular. Any lower and the birds would be lost in the white cloud reflections. I also like the ripples the span outward from the birds.
Wonderful color! Love the wiggly clouds! I've often wondered how birds don't sometimes get confused with reflections on water like they do with mirrored glass.
Really cool. Very nice colorful contrast to set them off, and without the ripples it looks as though they're on a ledge with normal clouds about them. A bit of a nice trick.
Quirky, but kind of fun. The water seems unnaturally solid in the blue areas, but I like that effect here. The birds look a little confused and that works well with the processing. Reminds me of a scene from Mary Poppins ;-)
