I'm not sure what the shot has to do with the challenge or the title for that matter... Technically the lighting is rather harsh. If you don't use the camera flash and use a tripod or other means of holding the camera steady, you will make a more attractive image!

Good idea, on the edge of keeping or giving it to charity! :-) I would have used a homogenic dark background and money could be a bit more in focus, otherwise I like the unique idea here.
