I agree with Alan, also wish you were a little lower or higher to get rid of the background line cutting though the gulls head. What camera/lens did you use?
Thanks for the comments. I agree re the placement. There was a slot in the rocks behind the bird through which some water was pouring when the tide came in and I was trying to time the bird posing with the pouring water. This one doesn't show the water but the pose looked nice. The gull was doing quite a bit of preening so the timing with the wave action was challenging. Lens was the Canon 100-400.
