I don't think your mirror is centered on the wall... You need a brighter accent color, maybe some curtains, and definitely a piece of art on the large wall on the left.

What is the purpose of this room?

Drapes and a creamy flokati. The mirrors make me dizzy. I'd prefer art on both walls.

I think the room is too small for an accent wall. If you do one you should remove the mirrors. I might like the sofa opposite the window and the two chairs facing each other over the coffee table, left and right of the sofa. Can't see how long that wall is. Add "accent" with great stationary drapes flanking the window.

A dark accent wall? What color? Dark as in like the wood tones in the furniture?
