I find this visually interesting. It makes me ponder, what am I looking at? The exposure seems a bit noisy and not real sharp, which detracts a bit from the overall quality. Nonetheless, an original artistic idea.
I think the hand is actually a distraction here, I wonder if it would have been possible to do something with just the play of shadow and light through the ripples... maybe with a rubber duck or something that it looked like it belonged there to provide a focal point.
Would have been more striking had the background color under the water been uniform. The brownish blob is distracting. If it was possible to get a clear shadow of all of the fingers, that would have been an improvement too.
