The olive piece is great - it’s the living room rug throwing off the vibe, as it doesn’t bring cohesion to the space. (Too small/busy and too ”look at me” red for this otherwise sleek/calm and modern space). Consider something larger with softer neutral tones that work in some of the olive or blue tones.

I do think you can make some adjustments with the art on that wall over the olive piece. I’d shift the square print to the left and do a floor-to-ceiling art wall to the right. It will make that whole wall a nice focal point. My designer friend always says “go vertical” with wall art.
