It's an interesting shot, and I can understand the moment (and the fact that there's no way you could have gotten the gulls to pose for you), but overall it is a bit weak. For one, there are basically 3 groupings of gulls here, and 2 run off the edges while the last faces off the edge, which takes your eyes right off of the picture! Also, pictures where the content is all around the edges and the middle is empty are generally not the greatest (though there are acceptions). You mentioned that you cropped it, so perhaps there is more potential here with some proper attention. From just this piece here, my advice would be to focus on the grouping of gulls on the far right side of the image, since they face into the picture and have as much sky as possible around them without the other gulls. With them facing and flying into the image and the other gulls not there to distract it would pull the eye in and be much more powerful.
