The ones already in are more than enough for me, its an entire city! I specially like that your ruins actually give me hints of what each should look like when fixed, and how most buildings show a clear footprint, rather than how many do ruins, which is throw random blocks around.

I am trying to stay true to your original design as much as possible, I only went creative with the castle, it was too monolithic when I repaired the walls, so I sort of lowere the ceiling a bit in some parts. (And I gace it quartz walls for more visual effect).

Just finished repairing all roads, close to finishing the outer walls, and the city is overall clean now, only buildings are left. :D
