Finished with my Japanese castle moc. Design is mostly based on an old Lego ideas by someone else (
https://ideas.lego.com/projects/93494a94-4229-4d86-bc0d-fb5209e727d4) but with some changes, such as reducing tenshukaku by one floor, raising lower wall height to make it scale better with minifig, and fitting it on the old royal knights castle baseplate I still have.
