I like this one better than most of the other shots like it. By not showing the glass, etc...its much more mysterious and intruiging and triggers an emotional response rather than just...hey neat, one of those cool glowballs.
I really like the design in this shot. It's a good composition - quite dynamic and a nice glimpse of colour on the right. Image is noisy though which will certainly impact your score. I think the only other negative as far as the challenge goes is relevance - this is more a photgraphic experiment than a scientific one.
