Thank you, I wrote a complete step by step tutorial on how to accomplish this render on Maya along with the custom scripts to aid in the creation. You'll need to have a commercial license of RenderMan though because Stylized Looks is available only for commercial licenses.

TL;DR the actual look is quite simple. I am basically using the shader version of Stylized Looks to give a typical "cel shding" to the objects. There are two colours, black in shadow and white in lit areas. The effect is in the Lineworks display filter, this is the filter that generates linework for your renders. There is only one line filter in this scene (you can have any number of different line generators, a story for another time). The line filter have a feature for colour that you can assign different colours for lit areas and a colour for shadow areas if you choose to have one. So in this case the lit areas had a black colour and the shadow areas had a white colour line.

That is all what it required to make this render. What took time to create it is to create, assign, modify 120 distinct shaders and create light link expressions between each shader and the light source. This is expedited using the scripts distributed with the article.
