In case you haven't noticed, this is actually hand drawn animation! (Don't believe me? Watch it again carefully!) At first, I too thought it was just 3D rendered using a NPR style... but, apparently, it's hand drawn and rendered using some new CGI techniques! I'm very curious to learn more about how they're doing this, as there's some very interesting stuff going on here.
