I like the simplicty of this image. I think if the backgroud material was a little tidier it would emphasize the rings more. The colour works well though. Also the focus could maybe be a little sharper.
As a photo this does not have much interest. A closer view of the rings might have helped. The wrinkle on the right hand side is also a bit distracting. It also looks like your resizing of the image added some jaggies to the image.
nice concept. I feel like the shot could've been pulled off better. The red sheet is very dirty, and the rings don't "pop" off the page, they seem out of focus.
