They kind of disappear into the background, don't they? I'd put a single, large, vibrant art work there (and/or, even better, where the mirror is).

I agree — one single vertical piece. The mirror has so many panes, I’d keep it simple for balance.

​You don't need those art pieces; there is a lot of visual activity happening and they're lost. I wouldn't replace with any art. I'd replace the mirror with art as the room is void of color, awash in neutral/beiges.

Thank you all so much for your help!

How about round picture frames ? A color from the chair cushions.

We can't see the rest of the space, but those prints would look fabulous if the wall were the color of the stripe on your chairs.

eta: I really like your mirror in your room, but agree some more color would be a nice addition.
