This is a revised version of the map I posted earlier. I've reworked the area around the balconies, rebuilding the shadows, adding a railing, and cleaning up some issues with the floor fill. I also tweaked up the nearby stairs. I think that area looks better now, but I'm not 100% satisfied with it.
As you can see, I've also added a bunch of damage to various floors. This is my first attempt at this sort of thing, and I think they came out OK.
Overall, I'm pretty pleased with this map, and I think I'll call it done. It's not perfect, but for something that started as a quick test project, I'm fairly happy with the end result.
