She is a classic beauty. Leave the patina'd copper . .add copper over the front door and side door cover if you can do it . . that would be stunning and patina out to match in no time. My other suggestion is to paint out the body (not the trim - it is great white) in a greige closer to the light element in your beautiful stone. Then the white side element / addition doesn't jump forward to the eye, but the gable trim, bay windows and dormer can stay white.

I think it is a very classy classic house.

The shutters are not the right size. They should be one half the size of the window. Yours seem long and thin. I would get ones for the windows on the stone and the gable, but not the double over the entry.

Other than possible painting the siding a darker color, I would not do any changes.
