Hmm, this doesn't work for me. While the picture is composed well, is well lit, is centered well..... the subject seems to feel too boring to me. Nothing really jumps out and says, HEY! Look at this! Maybe a different angle would help?
It seems a little overly sharpened and the light spots on the beads are a little distracting. The overall composition is a little boring with it being centered as it is.
