What an image! This is great, the birds are a awesome subject. I think the angle is prefect for the image and helps with the perspective category. The lighting, color and composition are all very well done. I think the top 100 is very well deserved, I would have defiantly put this shot higher up. The clarity of the main bird is amazing. I know in many art pieces they always state to use an odd number of subjects or placement but I really think the four work perfectly for the area that was shot. The only thing I could possibly see was maybe a little more focus on the sand were you panned out from, but I don't know how feasible that would in keeping your clarity on the main bird. Excellent work!
Good composition! It's a pity you can't see a little sparkle in the front bird's eye - that would have been perfect. I think I would have shown less of the sand in the foreground.
