Karwik (Noddy) made a nice setup of an old and run-down part of some city. Using the basic studs-up technique with varied colored plates and 1X1 rounds, he is able to achieve a believable texture on the walls. The dark blue also works surprisingly well.
Have you linked the wrong photo stream? I cant seem find this in Karwik’s sets.
He hasn’t posted it on flickr.
Looks like Detroit.
