Dude, I think this really makes me feel the expansion of the universe! The glowing arcs and swirls give it the brightness of stars. It make me think, "wow, this is what stars look like up close..." and the golden, purple, and cyan colours contribute to make it look really beautiful, like in a wondrous forest of stars maybe?? And the way the rays of light emit (or point to) the centre... I wonder, is it the creation of a new star, or the destruction? Possibly both, I don't know.
Not really as good as a critique, but there you go. I like this one a lot.
