I built this for Challenge V in GoH and unfortunately showed WIP pics before November 1st so I can't enter it in the CCC. Its a refugee camp located in an ancient dwarven city. Quite a bit of it was inspired by DARKspawn and Sirens-of-Titan.
Oh yeah, that looks impressively Dwarven, without having a single bushy beard in sight. But seriously, this is a terrific piece. I particularly like the "front door" shot, as well as the front of the "barracks".
