Add some bushes,flower pots,plant some grass, and plat a few trees with flowers

Not sure what zone or state you live in, so difficult to give plant selection advise. However, some basic tips would be to consider how your plan will look for each season. So, consider some evergreens along your foundation, a few flowering plants for the spring and summer and then plants for the fall. Try to mass plant using at least three of the same and if more continue with odd of 5,7,9 etc. I recommend using a taller specimen plant on the end corner and again on each side of entrance, right of double window and another of the same plant in the corner of driveway. You want to avoid a toy soldier appearance and the specimen plants should have more height than your evergreens. I recommend just the evergreens to left of the entrance. To the right, stairstep with the evergreens in the back, floweing shrubs in midde, and perrienial/annual plants along the border. Another idea for the large bed would be a small ornamental tree in place of a few flowering shubs. Remember to plant between 6-9 different plant species including the tree and flowers and consider at least 3 different leaf textures (ex. boxwood, knockout roses, happy return daylily). With the cool blue shade of your home, I would suggest cool flower colors such as pinks, pale yellows, pale lavenders, etc. I would stick with black or brown mulch and stay away from the red. Make sure to plant with spacing to allow for maturity and also pay attention to water requitements and sun exposure. Good luck :)
