This is a fantastic abstract. The colors are strong and complementary, and while the objects are kind of, well, nebulous, the little bubbles from the 7-Up give you something to get a sharp focus on, which you did fairly well.
Personally, I think that the upper-left half is a little dark compared to the lower-right half. It seems you have more light shining through the ice on the lower-right, which really brightens it up. I think that making the light gradient more uniform would be the only suggestion I have to improve this shot.
Evocative, attractive abstract. Good colors. Nice idea. There is a semicircular outline near the bottom of the frame that looks like a water spot that I would have cloned out. Given your title, I might have used selective color to maximize the blackness of the blacks, blues and cyans to give it a darker background and a more "space like" feel. Terrific job, though... you are to be commended.
Like this one a lot. The only complaints I have are the bottom left corner, where the lines look different and draw your attention away, and what appears to be a scratch in the lower left third of the photo. Great colors.
