Great picture. And you were very creative with it. Well done. I like how you can see all the individual grains of sand on the pitch black background. The young and the older hand make it quite poignant.
Technically, I think the ISO rating of 400 made the picture a bit grainy, which you could have made less grainy by lowering the ISO a bit, to 300 or so. Other than that, great idea. Good job :)

nice thought. I'd have taken out the shadows if I could...either move your backdrop out further, or use a reflector/backlighting. just my opinion. nice shot.
Nice idea (and departure from the clocks). I expect that a 'passing along' to the next generation is being insinuated. I think a grayscale/desaturated version of this might have been interesting touch as well. Good job!
