everything is plant heavy of the R side (windows too) a large growing shrub on the L, tall color pots (black ones now?- spray paint) placed on the walk way level with a variety of annuals, tall spike plants, collies and trailing geraniums on the edges. flowers would add color- daffodils/tulips/iris for spring, purple bee balm summer, alaskan daises mixed through out- last a long time & easy care.

And take the big rocks off the lawn. They look completely unnatural and it will be a real PITA to cut the grass around them.

As for the tree on the right near the sidewalk, remove the rocks, extend the bed to reach the sidewalk and plant it to a groundcover for shade.

Can't tell what's going on with the shrub on the far left, but it's not helping the overall look.

some ideas

Move and plant your shrubs at LEAST 3 feet away from the house. 4 is better! Read the labels and see how big they will eventually get when they max out their growth. Plant them with this in mind, give them enough room to fully spread out. Will look slightly sparse for the first couple of years, but you can fill in with some annuals, but eventually you will be so glad you planned ahead.
