Uh, textures don't support shadows, your mesh and normals do. And I don't mean just normalmaps, I mean your models normals in blender.
2nd from right uses shadows. It literally, without a doubt, uses shadows.
Not only does this model have customized normals via data transfer from roughly shaped like the head sphere techniques, it also supports AO mapping and normalmaps, meaning it does indeed work very nicely with shadows, with a customized toonramp to put it all together, the issue is every world in VRChat is different so why deal with specific configurations for each stylized setup when you can just remove the toonramp on one version and go?
