Add some tall shrubs like arbitrates near the house. Place trees in the yard in front of the large window to soften the view. Line the walkway with flowering plants to add color.

First thing is to lose the hose holder on the wall. Is there any bed between the walkway and foundation? I would get rid of the box next to the front door and replace with large cylinder or cone shaped container planted with a globe shaped evergreen(boxwood, ilex or aborvitae) underplanted with colorful cascading annuals. You could create an island bed off the corner of the walkway to balance the asymmetry of the front door. A specimen tree like a weeping cherry could anchor the bed. Depending on your zone and exposure some ornamental grasses might soften the front. Look at houses in your neighborhood for plants that do well in your area.
