I think there's something wrong with your image. It's very dark (and yes, i can see the gradient bar clearly) and extremely pixelated. Not sure what's up here.
Creative idea! R U in advertising? This is a good shot/set up. IMO though, i think that what you have going on with the contrast/saturation is although kinda neat, losing some crucial detail.
I wouldn't normally comment on a photo like this one but I can't help myself. I would certainly hope that a photo of a digital camera used for advertising a digital camera would be a nice crisp and clean photograph. I'm probably missing your artistic point with this shot, but I would certainly hope that the point is not to advertise digital imaging.
