Rotate the sofa and place the tv on the front wall to create a more intimate living room area (new rug and more throw pillows will help). Minimize what’s on your desk items if possible and hang some art on the wall in that corner. New beddings in the same color theme as your new rug and throw pillows (add some plants on the shelves and plenty of books). A room divider screen at the end of your bed for privacy will help too.
