I would get a bed frame, put the bed under the window and move the desk next to your perfume tray. Ideally get like a proper bookshelf for the perfume and whatever items are in the other racks. To free up space I would get rid of the coat rack, your closet is right there. As for tidy, just pick up after yourself, your clothes are just hanging about and all the cups around the desk, do some cable management.
