So as the title states this is a WIP, atm all I have are the foundations down for the castle walls. What I want to do is use some combination of Marble, Basalt, and Stone Bricks in the castle's construction but I cant think of any interesting patterns to put them in so I'm open to suggestions.
Here's a photo to show the base pattern of the outside wall.
As you can see I decided to go for a odd Oval Shaped wall and I am thinking about putting two towers at the sides of the walls.
