Alfa Cute. The only thing that is a little bothering are the darker stroks on the left house. Looks like a mistake?

Alfa Ok i get the dark line now. Just saw the zoomed out version. So from far its cool. From close up just a little less cool, but still cool.;)

Charlie Wrong in so many ways. Suggestion, look at old architectural elevations. Your line weights and shadows really need improvement. Also color choice? Why?
