Nice map! The buildings (Pagodas?) look amazing and I like the lower part of the map where the buildings are placed upside down. I'm guessing that was supposed to represent the dark side or the "fear intensifies" bit from that sign?
Also, I actually read the size of your map as LxWxH, but you placed it as LxHxW (which is the way minecraft does their measurements, I guess.) So yeah, it's quite a tall map. As for the buildings-- do you think that they would affect gameplay? I've seen staff mention things such as not having easy houses in maps from previous map submissions. But if they see it as a problem, I would fill the builds up with blocks (sand or wool) so that you can keep the aesthetics of the buildings in tact.
