Yes, I know it's ok. You know, shader that scatters with red light looks ok, but providing that you render a simple meshes (like this cartoon guy in your picture). Normally I don't use octane, but if there's a sss material I need to test that feature;) My main purpose was to create layered sss ...

For me the weakest point of this SSS shader is lack of the scatter radius option. I did some tests today (look at image). I tried to mix some refractive materials to fake sss layers - one of these scatters red, other yellow. Unfortunately it cannot mix properly. If only i found the way to amplify ...

You blended diffuse with an refractive material or mixed isolated materials for every scatter layer?

Michał, Poor studio doesn't affect reflection enough. Try setup Hdri or add few rectangular lights and some walls. Great modeling!
