What a flock - there are so many, I don't know where to look. A tighter crop with fewer might be better and less busy, or some additional clear subject may help as a resting place for the eyes.
Wonderful capture of wind (and energy). I can almost hear the noise that this group had to have been making. :) Looks like the technicals are in order. The way the seagulls span the photo lends nice balance to this. Best of luck to you in the challenge.
