IMO, any material substance has a texture. Water simply has a fuild texture. IMO, once again though, the presence of the model, land, and sky, distract from the fluid texture of the water. I'd class this image more as a portrait than a texture study. It's a very good portrait though. The model seems very unselfconsious for such a long exposure. P.S. I also commend her for holding still for so long. Especially when you consider that that area seems to have a lot of crabs in it!!!
