We did this same thing a few years ago. And I agree with the others since you have a small rectangular space,
you can't change the footprint into something with curves (unless you replaced the walkway). I would suggest a small/med. sized ornamental tree to the right, about 3/4 of the way down toward the drive (w/ white blossoms against the dark brick), then add very low ground cover. Then add seasonal color planted sporadically throughout and match come of the color plantings in large pots to set on a few of your steps.
Your house is beautiful.
