Okay, everyone specific people stop being richards. Here is some useful criticism:
Replace the tall 1x1x5 bricks you made the walls out of with bigger ones (you can find them in the same tab in the brick inventory)
Add some clutter to the map. Maybe some burning cars, barricades etcetera
The story is not an issue. For some reason it's ok when other people remake the hotel campaign, so this is fine too
The name is like the least of your worries. Focus on the build first
Add some trees and grass to the map, maybe even some buildings you can enter
