Nice shot but to me it looks like it is swimming downhill, I don't know if that is the way they normally set in the water, if it is an optical illusion, or if it is just me but to me it looks wonky.
Jeff, I also like the high key. I like the way the ripples are clustered around the duck and fade as you go outward. The duck himself is sharp, but I also think a bit of a CW rotation is in order.
