Progress on modular urban board

I've finished first nine tiles of my modular urban board - it's enough to make a 60x60 board for playing Flying Lead, but there's not much space for variation here. I'm quite happy with the colour scheme, though - and the example of the excellent Redemption City board by BaldLea shows that I'm not the only one who finds the white-and-green scheme eye-pleasing.

Ambush!

Metal pieces from The Scene were used for detailing the raised platform (I aim to make four such raised tiles).

Stairs were made using the method I've outlined here: http://multiverse15.blogspot.com/2011/01/sci-fi-corridor-tutorial-1-stairways.html

Duel between two gangers. Notice the manhole next to the sidewalk and the concrete texture on the wall.
