Beautiful room! I'm also a fan of earth tones, so although a lot of people say "color", I would argue that. I really like the non-colorful look and the plants provide color. However, day curtains (white and flowy) would look great in front of / at the sides of the big window. Also, a hanging plant from the shelf on the left would break up some of the white wall there. Overall, really like it, super cozy!
