High Bridge with Castle village and Gate house

My biggest project to date, 160m long and 64m tall, held together with hopes and dreams :). On one side is a small heavily defended guard house complete with balliste and catapult, on the other a small castle and village. The village consists of a small park, a 3 story tavern/inn, a barracks and jail house, a blacksmiths workshop, a cathedral/temple, and finally the castle itself. I would love some feedback on this project as I would like to improve my decorating skills as I feel my builds can sometimes be a bit bare or uniform looking.
