For those who wanted to recreate my fur shader
Basically, you mix the normals of the fur with the normals of the mesh. After that, you can stylize it with some compositing magic and adjust the shader for your own style and needs. Personally, I am still experimenting and improving my shader. I want my characters to have a great rim light, better performance in Cycles, and full control over the fur behavior. I post all of these stuff in my membership.
