Fellow writers: some quick advice?

So I created a character who I thought was great. She's kind of out there(she can talk to animals...sounds cliche but goes with my story trust me), slightly oblivious, funny in a discrete way...and then I realized she's Luna Lovegood's duplicate. She has a different appearance, and she does have quite a temper, but I really need something to make her unique! It could be anything that adds to the personality, and goes along with the basic idea of being different. The story also takes place in Victorian England if that helps :). So anything, absolutely anything, will be helpful! I just need to get out of a rut XP
