I've created over a hundred new custom 3D models including pictures, banners, doors, and furniture to make the castle more accurate. The grand staircase now has all of its paintings, as well as custom rails. I added all of the portrait shortcuts and given each one its own quest to gain the password, all of which are accurate to the video games. I have redone the grand staircase tower, and a couple of other towers as well. I've added a bunch of new classrooms and offices and detailed new hallways. I'm getting really close to finishing the castle, and when I do, I'll post a download.
