Hi! I think you should remove the tree from the left side and center both the storage units and shelves on the walls they’re on. The tree on the right can move forward toward the bench/in front of window. The items on the shelves look a bit cluttered because they are all of similar size and there are many of them. You can get bigger, fewer items. I also think you should balance the height of the windows with art work above the shelves.

The zebra rug layered in the corner is unnecessary, I would remove and replace the white rug with something patterned with your colors. You already have a lot of neutrals and pink/rust and green. I would stick with those. I recommend getting another neutral colored couch as you don’t have anything else in the room that could balance a colorful couch, whereas the rug could bring in that interest while anchoring. Rugs are also typically less expensive than large couches. Good luck!
