That's great, i love it.

Looking through with a critical eye, the only thing I would comment on is that the floor tile grid shows through the bearskin rug on the one room.

That having been said, this is one fabulous piece of work, I think you've carried it off well. I myself might have used more muted and darker colours, some places seem a bit bright for a horror setting, but really, that's a personal preference. If I sat down at a table with this map, I woldn't think twice about going "eep"

Nice!!
