There's another attempt to the DOD rooftop location. Today I added some textures to the monuments placed on the corners.

 

I added some metal texture to the pipes and to the roof floor. Although I'm thinking about changing this metal pipe surface to something different and maybe changing the shape of those 8 pipes in the row and make it have more "trumpet" opening.

The reliefs are not quite the same ones that are in the original game but they surely look similar. I found some Mayan reliefs and pictures in the web and made some kind of collage of it and put it together to match the monument's space.
