Decided to take a break from realistic shaders and go in the opposite direction. Illustrative techniques such as this one produce have good results but a lot depends on the style you are going for.This shader supports banded phong lighting, giving you a cell shaded effect. Below you can see regular Phong and Cell Shading
It also supports normal maps as usual. I had to remove the rim lighting for now, although i may find a way to re-implement it in the future. The specularity is sharpened to match the style and Lerped into the diffuse as I found that reads better for this style. A small amount of specularity is added into the diffuse on a constant basis, as i found it looks nice in the past.
