some critiquing:

TF2 shader: looks ok, it's getting there. Not a bad job.
PPE toon shader: it's a bit bright, and in my opinion needs a few more color change "lines".
Object based toon shader: I take it you're going for the naruto shader i sent so far it's looking good, it just needs a few tweaks, and if you can try to make the models look 2d using the shader, you'd have the full effect.
Gooch: i've never used this shading, so i'm guessing this is the proper effect. either way it looks good.
Full scene with shaders: Wow! very nice, everything looks fantastic.

Overall, stuff's looking like it's turning out well, keep it up.
