There seems to be a lot of noise in this. Was this a slow shutter speed? I like the designs in the glass. You may have done well to get closer to it, and not have it quite so centered.
This subject is probably a lot more interesting than it looks (from what I can see of the top section whichis properly lit, however the whole bottom half is in the shadows. I think it could have been really interesting if you had changed your lighting angle, and point of view. I would suggest trying to take another picture of it by putting the light from behind it, and taking your shot level or just below it, so that you can see the light streaming through - hopefully being refracted into many different directions
Nice idea. The image is grainy though, and could have been sharpened more. I also think that better lighting conditions might have improved the quality of the image.
subject out of focus and image overall is grainy. if the object were to be placed on a flourescent lighted background, it would help make it shine and glitter
