I like this shot a lot and believe it would benefit if you cropped the top part off an left the birds standing in a row...really cute birds. ((I thought they preferred water?!!))
I imagine the light was really warm, but I think the photo would be improved if the whites were less yellow. I realize that one does not just line up three seagulls and shoot them from whichever angle one chooses, arranging the lighting direction to suit the purpose, but I found the arrangement to be a little static.
