If by "noise" you're referring to the grain, that was addedTo me the background looks like it has some noise and there is a lot of "grey". If that is what you are going for, then you pulled it off. Personally I would have went with some more contrast to get some more shades of black and white in there.
Good suggestion. I've added the crop to the original post above.I like it except for the dead space on the left...maybe a square crop?
The second photo is actually a direct crop from the first one. The noise was already there, so the cloning job happened after.Did you clone before or after adding the noise in the second photo?
