My second concept for the EON Challenge. This is what I pictured the OTVs to look like as they traveled through the valley in one of the chambers. I had to go back and re-read a few things since its hard to remember some of the descriptions. I threw some facilities in the background and a bore hole in the atmosphere, although I think it makes the sketch look a bit too busy. I may do a widescreen lay out later, but I'm just going to keep putting different ideas together in the meantime.
