Huh very cool!
I think maybe a very basic background of a few big rocks would help give alot of perspective and depth to this while not taking too much effort, but I really like how dynamic the motion is.
Also you could probably milk the evolution time little longer without too many details if you where trying to hit a longer run time .
also narratively it taking longer might make it seem more impactful, but I really like what you did here, and the amount oh emotion you rendered in such a short animation.
Thank you for making this.
