The Star Of The Show

My main character is someone who I will detail precisely and make her stand out like no other, hence the fact that she's the star of the show. To begin my creation of her, I have to think and answer specific questions:
"Where did she come from?
How old is she?
Where does she live?
How does her life make her who she is?
How was her childhood?"
As of right now, my thoughts on her are simple yet complicated. Her name is Anna and she is 19 years old. She was abused when she was younger by her father and his friends. This incident has damaged her both mentally and physically which is the cause of the bruises and scar on her face (as well as on several other parts of her body).
She's lived trapped inside a life where she doesn't want to live in any longer. It's not that she wants to kill herself, it's that she finally wants to escape from her past life. As I stated on my first blog post, she will be wearing a red coat. This red coat will have a great significance in my film.
In my opening scene of the film, her face will not be shown until the last shot in which she will turn around and "face the audience" showing her reality full of bruises and scars. The red coat is significant in the sense that it contrasts from her past being emphasized by the location where this will be taking place.
This scene will take it a step further in getting the audience's full attention by creating a sense of mystery mixed with thrill.
To emphasize on her past life,  I'm thinking of including a voice over of my main character talking about the fact that she was abused since a young age.
