Anyone want to critique my character?

Hi, I just wanted to get some feedback about my character and where I need to add more on.

Also the background isn't completed yet; it's just mostly a summary of her current situation.

Yes lol

*Jessie Abbaddon
-Overview
Who calls her Jessie the young?
-Looks
Could you describe her body type better to me? Also she’s underweight by about 5-10 pounds. Is this intentional? What’s going on?
-Nature
Does she have any prejudices?
-Social
You don’t have to add this I’m just asking because I’m curious, but what’s her favorite weapon? You can always learn a bit more about how well or just how someone fights with their favorite weapon.
-Other things
She has an Irish wolfhound. Named Lemon. This is almost too precious. Man I want to live where she’s living. This seems really interesting i want to read this book.

Thanks to everyone who replied!
About her nickname, she doesn't remember who gave it to her.
She doesn't gain weight as easily as others which why she is a bit under average.
I'm still figuring out her prejudices.
She doesn't have any weapons; she isn't a fighter. :)

When is says personality type, try putting in her type from the Myers briggs Personality Test. It may help :) Also, always try to think of Who, what, where, why, when, how.

I'm not that familiar on personality types so I really can't put what type she is.
