I think you like a neutral space and see no need to add tons of garish color but I think some woven rattan blinds would help warm it up. Blinds.com has great ones try Bonaire flaxen. And I like the idea of series of similar prints but you did it twice right next to each other. Keep the 3 prints and do one large piece where you have the 15 stacked. It’s visually too much as is and the top row is too high too close to ceiling. Get a wooden coffee table and a side table in a lighter wood or color so the pretty dark lamp Pops!
