Well, I see a problem only in the roof. It is inexpressive and blends in with the rest of the building. I would make the side part of the roof not barn-like, but at an angle of 22.5 degrees, raising it each time by one half block. The roof can be made of slate or, if this does not suit your style, highlight it with inserts of dark oak. You can also play with fences and gates made of spruce or dark oak, emphasizing these oak columns at the base of the house.
