I'm not a fan of the whole "anime-style made outside of Japan" thing, but I think it can fit this piece in a way. I think there's a beautiful concept that deserves exploring, and I think that this is a very precise animation on said subjects (as literal or metaphorical as one takes it)... 4/5 for excellent idea, extremely satisfying animation and such... But in a style I think is too anime-ish. Nothing against those that can draw it, but if I want to see something in an "anime" style, I'd prefer to see something from the country who does it best.
