I think it would have been a little better to have focused more on one of the birds and maybe cropped out a little more of the cars. But still, cute picture!
I like the dispersion of the gulls over the grass - on lone one out front and the rest crowded into the background. I think there may be more than one good photo in this piece if you crop a little imaginatively I think you might find a few different pictures of equal or greater interest.
