I see a planet on the end of it's life span. It just falls into itself and is ready to just fall apart or explode at any instant. The lights around it are planets and stars, maybe a moon. Naturally anything dark in the background is the universe. Or at least I see this Nice work.
Yeah, it looks like bacteria to me too, maybe. Or perhaps some kind of plankton or a stray piece of pollen in freshwater. I think it's very attractive - no pretty colours but something very primal about it.
