Looks like a very cozy area! I assume you don't want the area to be too densely planted. Daylilies would soften the wall edges. Aquilegia (common ones that self-sow) would give airy look in spring. Hard to get the depth from pictures.

I'm going to try for some better pictures today thank you for the suggestions

Some more pictures

A couple of yellow itoh peonies such as Bartzella may make your bed really pop. Do you like hardy geranium? Orion is a really nice clump one whose blooms last a long time and bloom at the same time as the Bartzella.

Nicely done. It all looks professional and still cozy, as the other person said. I'll add my two cents--add something that reblooms so you always have a spot or two of color after the peonies fade.
