Fantastic Voyage - Environment testers

Under advice from Jordan, I began to explore the "feel" I wanted for my environment, with some quick experiments in tone and colour. Here's three of them, and I plan to do a few more.

I've gone for a muted palette, to enforce the desolate feeling of the place, and I've played about with putting barbed wire in a scene, just to see if it fits with where I want to go with this.

The result though, Is a smoggy, sickly looking place. I'm encouraged by these.
