TERRIFIC! Light is perfect, BG and colours are outstanding, and compo is nice but I might crop just a bit from the bottom, it feels centered but htere is more room in front of the bird and cropping from the right would tighten the comp to much. Congratulaitons on a very fine image!
I was just laying right down at the edge of a lagoon with the camera pretty much right on the ground. I keep my hand under the lens foot to allow me a bit more maneuverability.
The low angle and light are stunning Glenn and I like the composition instead of the fact that the bird is centered but the is not in tthe center of the frame. Very good job!
