The focus on the birds is 3D-ish. The contrast in the background seems kind of faded. I'm wondering why you changed it to black and white - it might have been nice to see in color. ?
I wish this were a bit sharper, I liek the idea of it. I think a lower angle that included less of the dark rocks would let the silhouettes of the birds stand out more against a bright background.
Nice. My only nitpick might be the comp seems a little too centered for me. The water cuts right across the middle of the frame and it seems to make the image more static than it should be. Hope that makes some sense.
