Hey Josh, the crop works well. I hope the gull didn't try to eat the starfish, looks like a bad idea. :) If you have, maybe a bit more space on the top and a slight boost in saturation.
Josh,
I agree with Axel that it needs a little tweaking with the light and color--some Curves would help make it pop.
Also, since you cropped it from a horizontal, I would go back and leave a little bit more room on the left side. Artie always suggests leaving "an inch" after an element like the leg of the bird, and just seeing a touch more would be nice.
