:) Just for fun, you can include the form of the character's Patronus, the form a boggart takes when your character is faced with one, the smell that the character gets from Amortentia...

And there are more generic ones, strengths and weaknesses, greatest fear(s), major goals, an explanation of the character's family.

I don't know if this is intentional, but you also don't have a "History" or "Background" section. Perhaps it's unneeded?
