This pic is mainly here as an example, to show off the door. I like the effect and the technical aspect of it, but as an artwork all it really has going for it is "gee wow neat" factor, not really composition. The lighting is weird because I was solely concerned with showing off the texture. Maybe it would be all right if the stone wall and floor looked more realistic.
Tech notes: The door is a complex grayscale-to-height map I created in Photoshop, using Celtic clip art.
