I already thought at creating this texture in Blender based on “Procedural Textures” and/or “Grease Pencil Painting”. Don’t know whether this would work, but Blender’s 2D features have made a big leap forward with version 2.8. I’ve already heard of Krita in the context of “Concept Art” and “Storyboards”, I think, but I’m not familiar with it.
