I have started with the next project: The Samurai Castle!
For now I am working on recreating 3D models from my old paper model that was never completed.
The idea is to have 3 basic levels/sizes and then be able to use variations with texture and roof geometry to make a lot of different versions of castles.
Each level could be double stacked as seen on the left and the ground area could be rectangular as seen or even square.
