It is a '90's builder interpretation of cottage/Craftsman. The half circle window is what identifies it as '90's (or maybe early to mid-2000's). What this means is that you have a lot of latitude about the direction you take it, and it sounds like you are on the right track with your changes. Definitely don't outline the gables with a different color than the body. Downspouts should be the body color as well. You have nice landscaping in the front, so good job there. So many people who post pictures here have neglected landscaping.

The home was built in the mid 80's.

Could you clarify what you mean about not outlining the gables? Do you mean that I should eliminate some of the off white trim I have in the mock-up? The rendering makes the trim stand out way more than it does in person. The trim on the front will look like the facia you see on the picture I posted of the side. I intended for the outside trim corners of the siding that was already completed to be off white like the facia, soffit, etc., Since the downspouts are all on the corners, they would have blended with the trim. The installer didn't do the corners in off white, however, and since many homes in our area are paint completely the body color in the back (without a contrasting trim color), we let it go.

Thank you for the comment about the landscaping! It has been a work in progress and I started with a blank slate. We have a huge deer population, so it's been a challenge.

I guess they started doing the half-circle windows earlier than I realized. :-) They were most popular in the '90's. The rendering does make the edges look cartoonish. I see what you mean about the corners being the same color as the body on the back of the house. That's what I meant when I said the edges should be the body color. The windows are lighter than the body which is customary - the corners don't need to be emphasized with a different color.
