Go into detail with what you wrote for the short description, as well as how the character acts. Ex. Shy, has mood swings, gets nervous easily, etc. Also, if this character has any relationships with other characters, here's where you can mention them. Or you can mention them in the character definition to show how your character interacts with them. For "categories" I usually just check whatever applies to my character - "love", "writing", and "fantasy" are the ones I most commonly use.
