I also have parts of my rework of the gothic fantasy castle from last year. I'm planning on focusing on the exterior more than the interior since when I made the original, a lot of the issues with the design came from having to make it work on the inside and outside. The main walls are close to done, next I'll redo the towers and then the architecture that is more customized and less modular. I'll probably also make 2 variations of this wall so that when they are next to each other the viewer won't see the same dents in the stone and missing shingles on each piece.
