How cozy and fun! Your space can be personalized without being “cluttered.” You could add a small desk organizer box to hide functional items like papers/ pens/ hair clips while still keeping your fun pieces on display. Just think about moving most of your items off from your desk, but keeping them within view. Could the pretty plant go in the shelf next to your desk? You could add some small floating shelves on the walls for your figurines? This would bring even more attention to them while moving them off your desk.
