Wow, this stuff is awesome -- I like a lot of the little details, the doors and whatnot... really makes them look legit rather than just a pile of painted recycling.
At the moment I'm trying to think of a simple way to add a slight bit of texture to smooth plastic. I usually use black gesso for my priming, which offers a tiny amount of texture, but not enough to really suit my needs. I've been eyeing those spray paint cans that make stuff look like rock/stucco/whatever*... anybody ever use it? Good or bad experiences?
* Krylon "Make it Stone" textured paint, I think it's called.
