As Lorchenne pointed out, there are a few areas where you could add on to your character. Just flesh it out a bit more and elaborate upon her belief system and such. I understand that some prefer to play it once they are there but the more you add on the more likely you are of getting accepted.
So a few pointers/helpful suggestions/character-making questions:
1. No one lives a "normal life", add in a little variation. What is the normal life like? What does it entail? What were some experiences that were out of the ordinary for your character?
2. Add a little to the personality, a person is always more than that. What does your character like to do in their free time? What do you believe about the crow's and why? What about killing humans fascinates you and how is your point of view different?
3. Why don't you see your family a lot? Did something happen and why? How recent was it? Will/Did your character ever get over it? Etc.
4. What makes your character interesting? What is so special about her? What does she have to add to this RP?
Again, just a few questions to help flesh out your character, the more you add onto it the better, it helps you understand the character and everyone else. Also, if you make your bio interesting enough then when people see your post in the IC they are more likely to read it even if their character has nothing to do with you.
