May be better to paint?

Here are some visual

Thanks for your comment. I do not want to do paint, as the whole house is open concept in this area and around the foyer, and all the house is going to be painted in a white color (off white, snowbound from SW). And we have a lot of art to add to walls.

So, just want to add an accent wall here. And thought wall paper will be good.

Is the artwork on right staying?

Yes, the artwork on the right is staying

Some wallpaper sites allow you to upload your room photo and photoshop the wallpaper into the photo. If you can do that, you should have an easier time making a decision. The wallpapers you have selected vary a lot in scale and it‘s hard to visualize as the wall is tall with an angle.

Instead of wallpaper, can you slide the couch and chairs over to make room for a statement console/sideboard with large art over it on that wall?

Consider replacing the chandelier. +1 to new drapes and rug. Maybe a tall narrow live plant or tree.

Thank you so much for your recommendations! Will see if the wallpaper website has that feature.

I wouldnt do a wallpaper accent wall.

The rug is nicer than any of the wallpapers. I would keep the rug and, perhaps, as others have suggested change the wall color.

I don’t think an accent wall makes sense here. I would get a new beautiful light fixture and rug.

I love your room! But I also vote no wallpaper. I would consider hanging a large sculptural art for that wall. Larger than your art over the sofa, which is wonderful by the way.

Agree with everyone with a no on the wallpaper. Either paint or another piece of art will work better since you are keeping the artwork on the right.
