We interrupt your regularly scheduled discussion of ephemeral rigging to bring you this awesome example of stylized NPR rendering. This piece really exemplifies what I love about the possibilities of a "flatter" style, even more then the Edge of Spider Verse trailer.
The only thing I might criticize about it is that the animation feels a little too smooth to me. It's extremely well done, both in terms of performance and in terms graphical arcs/poses, but I feel like this kind of look almost calls out for a variable pose rate to feel stylistically cohesive. But that's also an opinion formed by a history of watching traditional animation--this looks so good that I'm willing to be convinced that a full pose rate can work with a stylized look.
