Nicely done with the exposure having his wings as they are and retaining detail with the head feathers. Wish he had presented a better position of his talons.
I really like this pose b/c it's totally different from what we normally see. The top side view is wonderful, and I like how it forms a V. Might try a levels adjustment to the foot in the shade to see if you can give it a bit more detail. The head angle you have captured here is awesome. You can tell this guy is on a mission.
Agree with Marina. I loved the strong comp. Very well done. I know lot of folks dont like sqaure crops....but I think this will look good square as well. Since the bird is diving, it will look good as vertical as well IMO.
