Seawater swimming pool

On Binic beach (Brittany, France) one can find a sea swimming pool. It is filled during high tide and people can swim in it while low tide.
One evening my daughters and I were walking along the pier and the swimming pool started to be flooded by the upcoming water.

I made this shot and a few weeks later, looking at it on my computer screen, it didn’t seem like a very interesting image. I was playing with the curves tool in Photoshop when my daughter unintentionally pushed against my elbow and my hand moved, pulling the line of curves completely down.

I like the result very much.
