Very nice wing pose and light.
I have a completely opposite opinion from Alan's. I would crop out the water surface with the drops as I find it weighs the image down. My eye goes to the LLC instead of the bird.
Wish that smudge of sand/water wasn't in front of the eye.

...and here's another opinion....how about more water? I think that including more, combined with the trailing water falling off your tern, would tell a more complete story.
