On this update I've posted a work flow on how I go about cell shading and how things work in post processing. It's not a full tutorial but folks who's familiar with Photoshop can get some idea in how I construct cell shaded piece.
Tier 3 & Tier 2 patrons will have PSD attached so please enjoy analyzing the layer structure. I hope you can pick up few tricks and I actually don't mind people making use of the shown techniques and adapt and incorporate into there own.
Few more update coming before NOV! (Next time I'll post ART not guides and tuts.)
