Sci Fi Crawl Space/Access Tunnel

A detailed, original Sci-Fi scene. I intended this to be a crawl space, no more than 4 feet high... I just feel that it a the sense of more space...
Modeled in Blender, rendered with Cycles, a little post compositing in Blender & Gimp.

This scene is all my own design. Actually I was using it as concept art for a script I was working on and it actually showed me a flaw in the plot...more of that later.
