Great little building PFC.
This is something I have been trying to do now for some time. I have skipped my idea of building with styrofoam and have moved onto using styrofoam to build a mold for a building. This is a future project that hopefully will see the ligt of day soon.
The loose tiles on the roof really complement the damaged building. The whole thing has made a nice background for your dio as well. If I were to add my thoughts, it would be to make your next project more 3D instead of the 2D wall. The roof goes some way here, but some side walls make a lot of difference! Congrats!!
