Landscaping will give you the most bang for the buck. low growing flowering shdubs under the bay window would be a good start. start a planting bed from.the corner of the front walk and curve it around bay windows. Layer plants of different heights starting with ground cover like Thyme, ajuga, creeping phlox ,pansies, then bulbs and perennials like daffodils, irises, mums and shrubs at the back. Start with a flat or two of whatever annuals grows well.in your area. I would be inclined to enlarge walk way by edging it with pavers. It would look good to curve it from rhe driveway.
The big money change would be paint in a bit darker shade from the bricks. At least paint the garage door to match the brick's midtone. Stay with the white trim and the brick tones but try a bright front door. Coordinate it with plants like a red door with red poppies . Really it looks fine so don t worry about needing do a lot right away.

Not a bad house at all! Yes to landscaping. And I'd save up for a more attractive garage door. We replaced our garage door with a nicer looking one, & it really upgraded the look of the house.
