Why use a girl ?

We used a girl for our main character because we wanted to portray the character  as a victim of her dead twin to use a male would have been more boistrous and the audience would have maybe expected a fight or some male testosterone action.

We didnt want to give that kind  of image so we used a girl to make it seem more femenine and innocent, without being sexist, generally women are made to look innocent and more weak than males all over media therefore we thaught it was it was a good idea.
