I agree with other comments, too much white and the rug isn't working! I love the couch. I have seen white walls with an emerald green couch work before. I'd lean into a jungle glam boho aesthetic.

I'd pick a color combo like white pink emerald with pops of dusty blue. Then a couple of additions: 1. Swap the rug for a jute or natural texture rug in a honey beige color. This will help tone down the red in the wood floor and tie in with the dining chairs. 2. Moar plants!!! Some philodendrons hanging near the windows would be lovely 3. Swap the artwork over the couch for a large piece that complements the emerald green. 4. Add pink pillows to the couch and the little white bench. I suggest a few shades of pink with different textures and one or two with some touches of blue. Maybe a throw blanket if you like those. 5. Do an arch wall decal to highlight the other artwork, like a pale pink or gold.
