Paint the white downspouts a dark colour so they disappear against the stone.
For the street-side view, perhaps some wider trim around the window. It would be good to plant something between the shrubs. Something else to look at besides the expanse of stone. If it's too late to plant decent-size shrubs, I think tall grasses would look great. Very MCM.
Larger exterior lights are always attractive and relatively budget-friendly.
This is not an unattractive house - the stone gives it a cool masculine vibe. But some of the design choices (e.g. siding colour) don't bring out its best. ( LOL shutters??) Thankfully these are relatively easy to undo.
The burgundy colour in your stone would look great with navy or slighty lighter blue, for example in an accent colour to spray paint the chair on your porch. Or for the doors. It's a classic colour combination in men's clothing. like this
