The upper floor has a column that comes down on top of the doors, which looks wrong. I'd recommend either continuing the columns on either side of the door up, or just not having any. You might also consider resizing the front portion to be 3 regular spacings wide instead of 2.
Same sort of inconsistency appears
here, where the column comes up from the bottom and then stops. It makes more sense than the previous example, but I'd recommend picking one and sticking with it.
Also, using a wall clock for what I assume is a city hall is pretty funny, but I don't think it's supposed to be a joke.
Storefronts are usually continuous. i.e. the doors would likely be a part of the same "unit" as the windows with no structural walls/columns interrupting. It's easier to insert new storefronts when store owners change, and its also easier to provide an awning over both the door and windows. In your case I think you'll also find that moving the door inwards will make some nice symmetry.
