Thrifting was my life savior when it came to room decor! More lamps/fairy lights and a tapestry would fill that wall up without it being too much! Turn that big light off 😋 plants that look realish from afar, pathos plants are a good real plant to get, if you want succulents: get an aloe Vera plant from Lowe’s/HD and DONT water it until it absolutely needs it. I haven’t watered mine in 6 months!
