I see this has been posted a long time ago (almost a year now), so I'm not sure whether you're still working on this or not. If it's finished already, I would like to see the finished, textured product.
If its not done, the only thing I have is that there's one or two places where it looks a little like the mesh is falling into itself, but that could probably just be because of the wireframe view. Other than that, it looks fantastic.
This is too freaking cool. The large panels on the outer wall seem really bare in comparison to the rest of the place, but maybe it's nice to have something that isn't covered in stuff every now and then
