The first thing which stands out in my eyes are the hundreds of bubbles from this picture. I didn't see this before I think it looks pretty interesting. I like they way they stand on the die's black circles, some of them look like a fish's eye.
Likewise the multicoloured stripes from the background give some color to this piece and make it more eye catching.
What I don't like and you could improve is the right corner of the image. The bubbles there don't look realy good. The image looks a little distorted in that part and I think it could be better.
