my idea for a 3d environment was a coridor in an egyptian tomb which I had some major challanges trying to save and texture so here are two screen shots of the environment that was worked on in a render view from Maya. 

Idearly it would have been better with fire on the torches and more elements to the scene such as sand or skulls and Hyroglyphs on the walls but from these two angles you can see the basic idea.
