Nicely done!
Okay, for the next section. Quirks. What does she do that is a bit different? What makes her stand out? For example, it might be something as simple as refusing to ever go barefoot. Or, maybe she taps her pencil on the desk when she's nervous or concentrating. what makes her unique? Give us at least one thing there so we can get to know her a bit.
Boggart--we're not interested in what creature that boggart takes shape as. What we want to know is what is your character's biggest fear of all? The next sections are very similar. With the patronus, we dont' need to know the creature but we do need to know her very best memory of all. With the dementor, what is her very worst memory? With the veritaserum, tell us what her biggest secret is.
With the personality, give us a paragraph that helps us understand what kind of a person your character is. I'm interested in what makes her think and feel and act the way she does. Give us an idea about not just what she looks like on the outside, but what kind of a person is she on the inside.
Try those next and let me know if you need help.
