This isn't cel-shading at all
The technique is interesting, probably a big space and time waster but interesting. Cel-shading is a type of rendering of 3d models or animation too look hand drawn, you can usually distinguish it in some cartoons where there is going to be alot of movement of a complex entity (like a car or a plane) they will then render it so all the shades become solid and there are basically the two different flat shades. Go look at wikipedia for some examples, and make sure you know what your talking about before you write a tutorial.
