Thanks for the compliments

It's the default shader, I've just rendered it with GI Joe, and I think the bit of blue is from the lights... It brings out the details a lot better than just the standard lighting, but it can take forever to render. Maya actually crashed when I tried to render this shot in 640x480 in Production Quality, so here's the update in Preview Quality

EDIT: Rendering this took me 1:55 minutes...

Worked a bit more on the top and added some windows...
