I really like the wall, floor, brick colour scheme you've got going and the high entrances into the rooms, and the fans on the ceiling - and the way your living room is like a library room in a mansion ^^.

Are those Billy shelves? I have them in beech and enough books to go double rows by now, heh. But it's a bit better since I went ebook myself - however, the manga is ever increasing and as I only had certain shelves in mind for that and the other space was preallocated it is getting a bit iffy, should I round out of space once I've doubled everything up.

I think a rug that wasn't patterned would work better in front of the fireplace.
