Creative approach and theme used.
Background materials & props compliment this shot and are not too distracting.
Clarity & detail is good, and the lighting appears even. (6)
great idea, my only complaint is the seam in the foreground of the photo. I keep wondering if you moved the black items back further if you could have repositioned these items and removed the seam. Also the ring could be displayed with more of the detail showing.
At first I was having a hard time figuring this out - couldn't get a size context. The cufflinks looked like box lids, and at first I thought the ring was some type of container. Maybe I need to take a break! ;^) Now that I've figured it out...I really like your choice of background materials. The lighting is right on, as is the focus. This should do well. Good luck.
