I was on the beach at Jekyll Island, GA last week-end and was able to capture this image of an immature Ring-billed Gull. I took this about 4 in the afternoon with just enough fog to really diffuse the sun and give some really lovely light. I also reframed this as a horizontal, but for me the vertical was the more effective image.

If you have the pixels, I would crop a lot off the top, because I don't think it adds anything. It also will create more of the viewer's focus on the details in the gull, which you've captured beautifully.
I enjoy shooting gulls as well, but I don't see them posted in forums very often.
I think you could have improved this image by shooting from a lower angle. You still would have kept the reflection which is key to this image, but it might have allowed you to eliminate some of the large area of water above the gull. On this monitor (uncalibrated old CRT) the gull looks a bit soft and perhaps a bit underexposed, but that may be due to this monitor. Some fill flash may have helped by giving a catchlight in the eye.
I really like the textures in the mud. A lower angle would definately be a better approach for a more pleasing result. Gulls are the perfect practice subjects (exposure control, panning, habitat shots, close-ups...you name it and they can readily and easily be used in any situation!!)
