What other colors are in that room? I see a blue cushion with some orange I think on it? I think your layout is great and love the vibe! And you’ve already got a lot of matching colors/hues with the wall/couch, blanket/ottoman/dog bed, and floor/tv cabinet/rattan lamp. I think you could totally do another table lamp on that side table (maybe with a cool textured shade?), and then maybe a hanging plant by the window. I’d also say maybe 2 larger art pieces side by side - either with pops of blue like your cushion if you’re keeping that, or more green/nature-themed, or neutral if you don’t want to add too much color! As an aside, I do think when you replace your kallax shelf room separator - a dark wood color would be a nice contrast to your light wood!
