meh, its a hallway, most hallways are the same all the way down. They arent supposed to be fancy, they're just to connect one place of a building to another. I think that it is alright for a hallway. If it was a room then it would definately need more variation. But I've tried adding several things but they are turn out like crap, so im just going to leave it
@Fingolfin- i dont know who made them but i found them in an old version of the UTM. Just type "ulitmate terraining map" in the map section.
