Question Emulating Killer7(2005 Game) Shaders. Need some guidance

I am looking to replicate the shaders done in killer7 via the shader graph. I'm brand new to using the shader graph so I've been following toon shader tutorials on youtube. However, they don't capture the same look I'm going for. Is there any videos/tutorials I should look into in order to grasp the basics of getting this look via the shader graph? At the moment all I know is that the textures used are very basic/flat and theres emphasis on hard shadows. Thanks in advance.

A blender tutorial on how to replicate it (how to translate this to unity's shader graph?)
