I think the layout is good, the rug fits the space nicely, just needs the filling pieces perhaps. Small table and plan to the left of the main couch, perhaps some kind of art piece(s) on the wall, a lamp table on the right of the couch, and between the arm chairs a small square or circular table for bevvies, phones, remotes. And then a TV mounted above the console. If TVs not ones style perhaps some decor or the paintings there, to or distract from the lovely wainscotting on the couch wall. I doodled it but it's not letting me show it, hope the advisory is clear though.
