Look at same video, on this link.
Look at time 2:10
Look at time 7:10
You see, that film changed from cartoon 3D form, to "more Japanese".
Is there a word of how you anime fans call such art? The "more Japanese" part?
That is visible on 7:10 (and on thumbnail) but not on 2:10, you know what I mean. Floating hair, gigantic glassy eyes.
