Here is a piece I did recently. Some of you might've seen this in a 3d forum I posted at.

Took me 2 days to model and light the scene. Far from complete. The next phase I will play more with Texturing the darn thing right and tweaking the lights.

No I'm not demented, I dont dream things like this every night. I just thought It would be an interesting scene to light. All my models start from sketches.
