This is what happens when you are bored, have scrap pieces lying around and have some time. I made this as a back drop for my customs so they don't look so plane.
The cinderblock wall was made the same way I made the wall for Punisher's garage. I took this photo once I completed the Cobra Island ESU figures because it looks like they are about to raid a building. Mainly, this is just supposed to be an alley.
