I've experimented a bit while picking the best design solution for Fortress chapter & had different things tested. Finally I decided to go with very simple, army-like & non-artistic concept for it so that it would give it a more casual & barbaric look. I could try adding some statues or arches but I believe it would make buildings seem much more complex & art-driven. On the other hand I plan to have very artistic-looking, darker & more architecturally detailed concept for BUUMs Castle, with columns, arches & statues of weird-looking frogs
