They're very nice, although I'm not totally sure about the scale - the houses feel a bit too big, and the commercial buildings a bit too small. It's probably just a matter of taste.
Obviously it's early days, but the repetitive elements of the buildings, particularly the terrace yards and the high-contrast windowsills, start to lose coherence in big towns. More variety and more open space (parks, squares) would be good, but I suppose that will come.
Also, longer minimum lifespans on the buildings would help towns maintain their character as they grow, rather than having their larger buildings constantly replaced and shuffled.
