A bit orange and kind of dark. It seems that may be what you were going for, given the glare on the underside of the subject's arm - I'm just not sure that being this dark is right for the shot.
Great thought for a picture. A little blurry though. This is a hard shot to get clean due to the lack of lighting. Maybe if you could present more light but shorten your shutter spd. It would be a cool effect especially if you could see individual sand falling from the hand. Cool shot.
This is a tremendous idea that needs better lighting. I hope you don't get killed in the voting for being too off beat, but again, this is a great idea
