Hmmm. I like it for it's simplicity, and I also like the fact that you're presenting the image without a long winded (pun intended) title. :D I'm undecided whether I like the large expanse of sky or not. It's a bit mundane (even a small cloud or two would help - not that you can control THAT, he-he). I kind of get the impression you really wanted to include that third seagull on the left, therefore the larger sky canvas. Not sure that you're maximizing the 'Wind' story by doing this. Some that enjoy a minimalistic approach will enjoy this composition probably a little more I guess. Sorry for rambling, especially since I've not formulated any strong opinion on your photograph. Best of luck to you in the challenge.
Lovely image. Looks like a small bit of sensor dust that could have been cloned out but it doesnt really detract from the image. Very nice indeed. Bumping up.
