A solid middle ground entry which suffered most likely from "did not meet challenge" votes - the number of "1" votes indicates that pretty strongly. Since voters can't see your comments during the challenge, they'd have no way of knowing immediately that the substance here is bubble mix. That said, some seemed to think it was the psychedelic surface of a bubble, and the colors are rich and the focus is pretty good, with good even light.
This picture somehow makes me...nostalgic. It reminds me of something from a long time ago, but I don't know what it is.
It's excellently done, by the way.
