Frankly, this is disappointing.
I initially thought that this was going to be detailed and of very high caliber. From what I've seen, though...
you're duping a bunch of boxy and simple buildings everywhere.
I know, I know, the old "WELL ITS BIG SO DETAIL CAN'T EXIST" excuse.
But if you're really using this to film a movie, you'd be far better off taking the time to make really detailed builds of the sections you need. This is just yuck all around. I can only imagine that if it looks like this from the overview, it must look even worse close up.
It was a valiant effort, and a neat idea too, but definitely lacking in execution.
