In Blender this is just a textured plane with a mesh deform, swapping expressions on a spritesheet. The eyelashes are also textured planes. The clothes and body are animated with mesh deforms too to get those exaggerated keyframes with fluid animation. Most of the shading he uses is baked onto the textures with simplified normals to get those clean smooth anime shadows, and most of his outlines are painted on the textures but sometimes he uses a solidify modifier with a black material offset and flipped normals. These are easy to do once you get the hang of them. You don't need shaders.
