Need more info. How large are the areas? What room are they in? What is the decor in the rest of the home?

Have you considered removing that detail and gaining a wall for furniture and art that isn't from a big box store? That's about 9 feet of wasted wall space, IMO. Sorry, I'm more about function than form. You can still have a nice art installation on that wall.

This wall is adjacent to a walkway. Our furniture spans the other sides of the room and wouldnt work on this wall. We are not only open to art from a “big box store” which is why im asking for specific ideas.

I bet you'll find something here. They can reverse the image too, if you wanted the same thing on both panels.

All over this country there are artists struggling to sell their work. Beyond traditional galleries they are online, at art fairs and showing their work thru art colleges. For those spaces think about investing in original art work that speaks to you. It might cost a bit more than manufactured décor, but it will personalize your home like nothing else can. Here's just one such site:

Can you clarify what you mean by 77”L 56”W. what is the height and width of each of the two spaces?

Sorry-77”Height 56”width

I really like the idea of buying local artist. A few years ago I bought three art photographs at a local craft fair. The were nicely framed and matted by the photographer.

I would paint the inset the same color as the wall.

You could do a gallery of art. Or you could remove the two frames and just do one large piece.

More pictures of your space will help…for art to show best it should integrate and enhance the style of your home…

Art is really personal and when looking for two large pieces or just a few large pieces they really need to bring you joy every time you look at them.

What brings you joy?

My home is filled with wildlife art, but I spent 25 years in the humane industry, have always loved hiking and horseback riding through the mountains, and spend most of my free time outside, prefer gardening to housework and love all aspects of nature from plants and insects, snakes and birds. My art reflects who I am.

Without knowing anything about you the best anyone can suggest is what they like or what they think will go with your furniture.

Following.

Do you have art on other walls?... if so, the mentioned idea of mural or an accenting wallpaper sounds good, to uniformly fill large area.
