Well done, I like the style of building, and I always appreciate a good MOC made with few pieces (seeing as I have (relatively) few pieces myself). I think I could see this as a worn village, or ruins (with minor adjustments) in medieval times. Also, the entrance is very nice.
If I were to make something out of LEGOs, I would probably use LEGOs. Pretty advanced stuff going on up in my head.
Looks great! Even seems like you get a lot of play out of it.
For some reason, it's annoying me that it's on the floor, probably because I've taken to keeping everything on a desk/table in my mad post-Brickcon cleaning. Anyway, keep it up!
