Your rug adds to the severity of the room, so I replaced it with something more properly sized and more muted with an overall pattern. These large walls and oversized sofas will not be satisfied with dinky art, so I gave you a canvas that is 6' square. It looks like art.com's Loft Art is currently 40% off, so right now it's a bargain. This size and these colors give you plenty of impact without being garish or overwhelming.
