This is a Zbrush sculpt I turned into a mesh only 3D ink looking art piece.
Some painting and generation of the ink look was done in Substance Painter and then in Zbrush turned back to mesh only so there are no textures at all used. The ink strokes were done with a waves brush I made and some smaller strokes generated with fiber mesh. The 3D outlines effect is done through the copied mesh with inverted normals trick while I also gave it some distortion.
This is the original quick sculpt I made with Sculptris Pro, I basically sculpted from a sphere with a fur brush I made. Then some clay buildup for furless areas and some Dam. Here the fur is not amplified yet for the Ink generation.
Here it is on Sketchfab:
