MY first thought is get some solar shades on those windows before the sun ruins your floors. I have no idea of your style but why not wallpaper? Or even a mural. As for art Art.com has great selection often in different sizes too. I ahve never been a lover of a mixed wall of pics and frames .

This is a mural you could even do this with paint

I had never considered wallpaper, I am going to explore that more. Also, appreciate your suggestion about the solar shades.

Something like this would be beautiful!

I dunno. I always feel like these mass produced art pieces make your home feel like you live in a generic hotel lobby. Go to art fairs in your area. Buy a print or a painting you really love and have it framed. Yes, it won't be cheap, but it will look so much better and reflect your personality.

Alternatively, you could find a textile hanging to put there, or even a modern quilt.

I, too, would recommend a quilt. Some old ones look very modern and abstract.

While a quilt would look great, that is not a good spot for one because of the sun.

I've been lucky shopping Wayfair.

Try art.com. Think about who your favorite artist is. Matisse- Monet- Picasso-
Is there opportunity to make it larger than life?❤️
