This was an experimental short animation I made using Blender's amazing Grease Pencil tools.
Coming into this, I really wanted to create a hand-drawn, sketchy style for the lines and materials, and integrate a rigged 3D asset with the 2D Grease Pencil objects, aesthetic, and animation style as seamless-looking as possible - the tail/creepy hand is an armature-modified 3D mesh object; everything else is a GP layer, drawn by hand.
Based on designs for Cool Cats' SideKX character, "Bones" (https://coolcats.com/news/sidekx-everything-you-need-to-know).
