Wow! Really cool. I gave it an 8/10 because I think there are a few things you could improve...not sure if you intended for the non-level horizon but you could level it, and some photoshop curve adjustments and it would be even better!
Having a straight horizon line is real important in photos taken of any ocean type scenes. It would be an easy fix too. I like the idea of all the birds...above the rocks and water. There's a nice texture thing going on with that. Maybe sharpening the photo a bit too would make it stand out more with the blue sky. Verena
Just as had been said already- it bares a remarkable resemblance to that Hitchcock film! Hope they didn't poop on you while taking this splendid picture!
