Looks good. I like the city walls and the town layout. I'd recommend varying the size of blocks inside the town, and the houses themselves. At the moment it looks like everything within the city walls is the same size which implies the same economic level everywhere. Also, the roads inside the city are massive compared to the roads outside the walls. I'd expect roads outside to be wider, as space within the city walls is at a premium.

Love the colour scheme and the details in the farmland too. Very nice!
