Bi-Weekly Challenge! - Rooftiles

This time I'm deviating from the reference, and going a bit crazy. These will be (probably :P) weathered, titanium tiles. Ill make some neat fasteners, perhaps a layer beneath for missing panels, and perhaps even emissive parts or solar cells on this. Just to see how far I can push it and still have it look convincing. Current renders are just a quick start to get some damage and heightmap going on.
