uhhh
ill try to keep this simple.
Animation & style - not bad, but seems inconsistant from the person dying to the person just born.
Meaning & concept - No offense but from watching this, & reading your comments, how does another person dying from another dimension and being born in our dimension give symbolic meaning to life. It makes sense in theory but for what you have showcased, that did not come across. When i watched this, it showed no specification of different life forms living on seperate worlds, and had simply was way to short and minimalistic to convey any real meaning besides the fact dead things comeback reincarnated.
I liked that you tried thou and support you in your future animation projects.
