I love this photo. I actually had a similar idea one day on the beach myself. I added it to my collection. Although I like yours better - so i'll be trying that idea when I go to Cape May in the summer.

Good job taking two things as simple & overlookable as sand & feet and creating this photograph.

you recommend any reputable contests? There's so many and I don't trust most of them.

Your local State fair, and watch for contest in your newpaper. I have found them to be the best.
