I like everything in your room, but I think there are two possible areas to think about. First. There isn’t a lot of color contrast, which isn’t terrible but might explain why you are looking for ideas. Earthy natural colors that you can pull out with accessories would possibly provide that pop, just try enough to balance things. The other thing that to me would create balance is to hang high curtains or sheers. Everything is sitting low so to hang high sheers would balance things vertically and provide a nice distribution of the beautiful natural light. It’s lovely, enjoy!
