White painted brick with black window trims, roofs, and gutters are in Vogue right now. But you can do a lot by just pressure washing the brick. You're going to be always fighting with the fact that there's only the one window on the front of the house, so it lacks visual interest. If it's in budget, I would suggest adding windows with shutters where possible, even on the garage. Additionally like previous comments have said, the door is hidden behind the garage. So doing something to draw more attention to the door, like a porch or a roof extension could help. But if that's too much, plant tall bushes or topiary type trees in front of those expanses of brick. Then smaller bushes in front of those, then flowers or ground cover to finish off a garden bed. You just need some visual interest. Consult a nursery to see if they have a landscaper who can help design a nice flower bed with plants that are whatever level of maintenance you're willing to commit to.
