I'm really not into those arched windows with the shutters on this house. I think it would look a lot better if they were square. I also think the outside would look better with a different pattern/siding on the outside. I think it has to do with the separators you see between each floor, particularly the very top one with little space between that and the roof. It just doesn't look right to me. I would also remove the fencing that's not attached to the porch. I think it is a distraction for what should be a big and beautiful yard. Perhaps you could replace it with one of the very short "fences" that would typically go around a garden instead? I think those don't block sims from entering them either, so it would still separate your walkway from the grass.
Besides that, I think you're off to a pretty good start. I'm liking the overall shape of the house and how spacious it is.
