For sure I would paint the narrow white strip around the garage door and the front storm door bronze. Assuming your chosen roof color, I would probably paint the gutters and all of the remaining trim bronze. The new windows should be bronze and they should have some kind of shutters because most of them are so small. I think casement windows in bronze would suit the house. A more horizontal style of shutter like the ones in the sliding shutter picture would be nice. I was up in the air about the soffits but perhaps someone could do a rendering showing them bronze as well to see if it all looks too dark.

one other idea but it would be major: I like the bricks for the walkway, but replacing the porch and the rounded part with wood would look better. I wonder if a concrete porch can be clad in wood (maybe that would cause a water issue) or if all that would need to be demoed first? also, I like your idea of cedar around the windows, but really, you could probably just get away with painting the white trim a dark color, like in the first photo I posted above. it would especially look good if you redid the porch in wood.

The existing dark bronze color of the siding is already a color often recommended for combining with red brick. Note that what you have already leans ever so slightly green (or so it looks on my computer) but in a very muted way so there is some contrast between brick and siding (green and red opposite on color wheel), but not so much to call attention to itself. I like it!!! However I think siding color should be considered in relation to roof color - since metal roof colors are so limited. What are you thinking for that? Perhaps a similar bronze or greige for the roof....Ive seen some which are more metallic in appearance vs. flat color. And then siding color simply becomes something that is different from roof color but closely related (ie darker, lighter, more grayed, or less grayed). I agree with the above posters that it is a beautiful house in a beautiful setting and it is that deck that could use some attention. Use deck structure (if sound) but maybe replace wood handrail with wire or glass as suggested above - the idea is to lessen the obstruction to the view.

Can you repost pictures that can be enlarged, particularly of the house itself.
