I really like your town, it looks like it had a natural progression like a real one. Since you want to build a realistic town i suggest to build a market area with all sorts of different stalls(it's more easy now since they added all sorts of clutters and decorating options), and a commercial hub with a warehouse and a little stall for the travelling animals to rest. It would be a place where the merchants can come and trade. Since you are near a river i would suggest to also create a commercial port with stalls that sell fish, cattails, clay, exotic goods ecc... , but i saw that you hate building in water so the decision is up to you XD, but i would give your town a really nice touch.
Keep building like you have done and good luck for the development of your town !!!
