Wow! It looks great, just a couple of questions:

- does it use a toon map like most toon shaders do, so the shine could be modified?
- what shader model does it support?
- how is the framerate in fullscreen?
- is it possible to modify how thick the outline is?

Overall you've just about got it. As a matter of fact, the mech shader is so good i'd think about a patch for PreVa

if you make the normal-mapping i'd make it optional, a second version if you will. It looks like you got the 2d pass perfect though, it definitely has potential . Both the shaders look great, there's just 1 issue. The black shadow around some parts is one, but if it uses a toon map this could be changed.

Overall they look great, and look better than most toon shaders, i just think that if you could do that one thing, it'd be perfect.
