flow of time

I really like what you did with this. My favorite parts are the color, the capture of the sand falling, and the shadow along the wall.

I think in order to improve it would require digital editing in order to make everything except the sand in black and white. However this would take away the "photography" title from it for sure, and instead make it more like a digital piece.

Another interesting thing to do here would be making the light come from the same place the photo was taken, except much lower, elongating the shadow on the wall and making it feel more dramatic.
