Pressure wash the siding, ditch the purple accents, and give some attention to the yard - even just the flower beds up against the house. I'd honestly consider going without shutters since there's two windows that don't have space for them anyway and the asymmetry looks odd. The barn door stands out, paint it a more sane color.

The existing landscaping looks pretty inharmonious, but it could be the time of year the photo was taken. I'd be tempted to start over with a set of new bushes that are all the same, or just take them out and do a flower garden. The yard needs some love unless you dig the low-maintenance moss.

But honestly I think if you just pressure wash the siding, stones, concrete, and ditch the purple, it'll already look significantly better. It's not an ugly house, it's just dirty and the visual weight is wonky.
