Hi Ursula: You did a great job capturing the gull with the "catch." However, I think this scene would have been more powerful had you photographed it from a lower angle...if that was possible. Also, I find the crop a bit tight all around and not sure if the ore "pano" crop works here. If you have more room in the original picture, I think I would try giving it some more room all around and see how you like it.
You did well with the exposure and you have nice details in the feathers. I like the yellow in the bill and the orange of the mouth.
