sure, but maybe if you would want to share an idea of what you want to do. As I could already say, canals, water, bridges, crosser buildings (like the bioware city crossers), raise/lower terrain, maybe buildings that connect/interact with the raise/lower terrain. building crossers that connect with the water/ or canals, waterfalls
the more complex could be, chinese temples, walls, walkable walls, shinto shrines (japanse temples), trees, staircases (like the really long staircases to temples), Gates (Arches), statues, doors, Towers, boats, docks, small bridges, creeks/streams/aquaducts
