Oh my God, this art and 3D rendering style is divine...you MUST teach me through a YouTube tutorial how to achieve this "sketchy" shader look in Blender Cycles. Or better yet, sell it on the Blender Marketplace (preferably in a way that helps fund the Blender Foundation itself)!
The character designs and animation/movement style are 100% unique to you, though, and I'll just have to accept the fact that even with your lovely shader node setup, my animations will inevitably look different in one way or another.
EDIT: Just read the actual description. You're waaaaay ahead of me!
