As a tip; if you're gonna make an Orange map that's perfectly fine by me (and don't let anyone else put you off it), BUT please use some other textures than JUST orange. There's different variations on the orange (a wall one, a crate one, a hallway one etc.) and there's also other greys/reds/blues to give contrast. Especially since this map's at night it looks very difficult to distinguish the geometry, never mind looking extremely bland.
