A variation on Andrew Price's Subway tutorial

Hey there, I have to get back into 3D, so I’m starting tutorials again. I’ve been doing things with blender on and off for about 5 years, but have never done anything too serious. I guess I know what I’m doing when it comes to modeling, but have never tackled lighting/compositing. Probably due to my fear of all the noodles.

I started Andrew Price’s subway tunnel tutorial to get started. My goal is to get a post-apocalyptic ‘Fallout’ effect. I’m planning to add some more props along the way. C&C is, as always, more than welcome.
