I am making a medieval castle/fortress. I have almost finished the main wall, and I still have to add the main gate.

I am also planning to build a moat around the outside of the wall. I want to put some kind of a castle inside the wall, with a bunch of houses and a cathedral also. Any suggestions would be greatly appreciated.

I have also built everything so far by hand, with no commands. The only commands I have used are to turn off weather, stop mobs from spawning, etc., but nothing to help me build faster.

I have spent about 6 hours so far building, and since I have placed 15, 413 stone bricks. I still have to age 3 of the sides of the wall, but if you wanna see what the wall will look like when it is done, I finished 1 of the walls and the 2 towers that touch it.
