it looks like you were trying to build something old
old things have a very elegant feel to them, having very special designs which exaggerate something, such as a window ledge, or a roof, sometimes with intricate carvings in them. usually some people would refer to this as "detail"
I'm not sure if you'll understand what i'm trying to say, because this is my view on old style buildings
the "details" you tried to put on your building look very random and mismatching
