A siding color that better complements the brick, remove the shutters, more interesting garage doors, change the storm door and better landscaping. Maybe a medium gray for the siding if that is what the mortar color is. A bright color for the door and larger light beside it. But again landscaping is going to help alot.

^ agree, def remove the shutters and add a friendly pop of color for the front door - landscaping will help a ton

I think split level/split foyer houses look better if the brick and siding colors are very close, so you're already there with the siding color. If it's not quite right I can't really tell from the pictures. That's something you have to judge in person. If the siding was darker it would make the house look top heavy and emphasize the different finishes. For me this isn't desirable, but maybe others like it. As the other commenters have said, the shutters are unnecessary and need to go. The garage doors could be darker, not white, and windows in garage doors always look better. An imitation natural wood color or something leaning brown would look nice with the brick and siding.

another vote for removing the shutters.

I would also clean up everything at ground level. the lower level windows should be a feature, not hidden.

I would paint the garage doors and siding SW Polished Mahogany it's richer than a brown.

Have you just bought it or have you been there a while?

I agree that new landscaping would be good. It's late in the year to start where you have snow, however, you can trim the two shrubs lightly and remove the yard decor scattered along the front. Then buy a hundred daffodil bulbs, a lot of compost, and bulb fertilizer. The daffodils will be welcome in spring while you plan for more permanent landscaping. They can be moved when new foundation plantings are installed.

Google images for ”contemporary modern house”. It shows some of those boxy modern designs that may give you some inspiration, if you like that style. You already have some boxes on your facade.

I have no idea how practical those designs are for your house, but it’s worth taking a look.

You could also get a company like brick & batten to work up a design for you (https://www.brickandbatten.com). It’s a bit of an investment.
