Describe the character’s bedroom. What sorts of decorations are on the wall? What kind of furniture does she have? What sorts of collectable items are displayed? Is it messy or clean? If she shares a room, what does her roommate’s side look like? What contrasts are there? If she shares a room, does she have her own space somewhere? Knowing what your character does with her own private space can tell you a lot about her likes and dislikes but also about her personality and even how she relates to other characters (if she is really organized and her roommate is messy, how does she handle that?).
