I used a .6 GND to knock down the brightness of the sky so I could capture more of the structures, but I had it pretty high up with just a minimal differentiation.
I've cropped this image eight ways til Sunday and I find that cropping all the foreground just makes it buildings floating, which while interesting suggests nothing as to their origin. They could be on any hill, anywhere. For me, the connection to this specific place, overlooking the ocean, seated on a dismal plain sets the stage for plenty of intrigue and mystery.
