Nice colors. Shadow her is a major distractioninmy opinion.
The overall size of the image is on the smaller size at 432x213 pixels. The file size is also very small (27K), which will hurt it's overall quality.
We are allowed 640 pixels on the longest side, and up to 150K. Using as much of the 150K as possible will only help to not compress the image. If you need help in understanding or making these happen, please don't hesitate to PM me and I can give you some pointers. (5)
Having the strong lighting is good, but the harsh shadow is not so good. Either a reflector to shine some light behind the bead to reduce the shadow, or selectively lightening the shadow would help.
small & bottom is blurry. Lighting is casting a very strong, distracting shadow. - hope you overcome the likely low score and continue to participate and improve.
The subject appears very "busy" to me; perhaps a different subject could have helped.... The shadow doesn't really add either. It could use some sharpening too. good luck.
