Hey, I made a piece of sheet metal that may have the look you're going for:

I did use a seamless texture form textures.com , for a bit of the grain on the metal, but if you want, I can send you the node setup and link to grain texture used.

Cheers!

Hm...I'll check out something for aluminum foil. I'd think the standard glossy and diffuse could do something, but I'll experiment with some grunge textures and see if I can get something metallic-looking.

Well, I was going for an Al-Foil look. The stone was really just experimenting with bump maps, so it was never ment to be out of stone :P

Tiffis, what kind of look are you trying to get with the stone? Are you trying to get a marble counter top look, or a rugged cliffside look?

I don't know too much about engines, but the modelling looks nice, with all the pipes, the fan, and the other smaller details. I have a question on why the engine is carved from the stone though, is it functionally realistic, or just for decoration?

Depending on what kind of look you're planning on giving it, I might be able to find an appropriate node setup for it.
