Looks well from the top.
well for the ufopedia it would be nice to have more detailed models, although for map depending on the scale of the model we may not notice any anyway.
I guess the black "windows" can be main exits for UFO interceptors and reconaissance planes.
How about an antenna on the top of the main pyramid ?
Also, maybe an alternate version where all sub-pyramids are linked by a small wall, that may be nice too.
Just simple thought for Winter.
