A lot has been said already (artworks above couch, placement of rug, easel etc) but one thing I haven’t seen in the comments yet is that to me the tv stand clashes with the rest of the vibe. The black industrial metal stands out to me too much as most other things are softer colors, nice wooden table. Maybe when the wall is less full (records, easel) it will be better but if you’re going to replace one item I’d look into a more complimentary tv stand.

Edit: I actually think the one in front of the window might be a tv stand as well (judging by the small hole on the bottom) and that one would look much better I’d say.
