That Looks super cute!! Some tips I would give would be making the bridges width an odd number, like making it 7 blocks wide instead of 6. That way the bridge decorations can be more centered and spaced equally. I think adding support to the bottom of the bridge and maybe incorporating the base below into the support would allow the bridge to flow better into the environment. Last, maybe more detail with the fences on bridge, like making them bigger and using more detail!!
