Very nice shore shot. I really like the contrast between the wet and dry sand. The sky is quite beautiful and the bird is a nice touch. The only suggestion I could offer would be leveling the horizon. This excellent image is well worth the effort.
I like a nice beach scene, this one could be improved with a leveling crop so the Ocean dosen't look like it's flowing down hill. Also, increasing the color saturation might give the photo a little more pop.
The gentle colors are great, especially the way the sky is reflected on the wet sand. But the comments about the horizon are right. My first impression was of an impending tsunami - a bit unsettling. A level horizon would preserve the beautiful serenity of this scene.
