Would love to see a level horizon here. Interesting shoes and I think an interesting idea. Good potential. I like the sky color, but not so sure about the bright pink sand? Focus is good on the subject and dof makes it interesting. I wish the photo wasn't so divided between the blue and pink.
I like the colors but maybe a different angle, not the lighthouse thing in the background (it's kind of distracting), and that sailboat in the middle along with that red light. Just some things I thought you could work on. But great idea!
