This is a render test I started last night to see how closely I could match a colour key I made a while ago  using Maya with no paint or manual retouches, just render passes and compositing… (Note i wasn’t trying to match the model so the geomitry is a bit low rent) Its all rendered using mentalray with bog standard shaders, I used 4 passes and saved them as 32 bit .exr files and comped in nuke, I like it as a test, I might do another…
