Oh my god this is beautiful! I really love the fountain and the symmetry of the base. The building also looks very comforting haha. It gives me a slight feeling of you being in the medieval times! Very classy and nice.
I'm going to disagree about the use of cobblestone and stone slabs; I personally love them there. Your town center actually looks pretty nice. On the inn, I would use glass blocks instead of panes (but that's just a personal preference). Also, I would add an overhang to the middle, separating floors one and two. You can easily create this by adding stair blocks on that middle line that goes through everything. You could also use upside down stairs right underneath your jettied windows to make them seem more stable.
Not too bad for what you've got so far; if I may make a recommendation, it would be to replace the inn with a town hall or something (which would really just mean changing the interior). In most cultures, inns aren't found right at the center of the town; rather, they're found closer to the outskirts of the town, right near the entrances because weary travelers will find them easier.
