"Atelier" is a study I did to try to obtain a hand-painted look from a 3D render. I used a single black-and-white brush texture that I had drawn and created a node group based on that to be used by all materials. The shader outputs diffuse and normals so it can be used with Blender's other shaders as well (tranperant etc.). This was fun to make, hope you like it too!
