Should have added room has been taken apart for ceiling redo.

I like accent walls, but since I don't know how your rooms are joined, it's hard to comment on whether you should have one or not. If you do an accent color on a giant wall, I'd suggest perhaps just a darker shade of a neutral that is on the other walls since the color now affects a larger area.

I like it as is...however, art on the colored wall. Oh yeah, and new chandelier.

Yes, an accent wall but with wall paper not with paint, so the wall won't be so contrasting with the antique white, and change the chandelier.

We really need to see a photo of the wall in question since the one you show above has apparently been expanded.

Just change the light fixture.
