Script to Screen: Character designs (features, hair)

I'm drawn towards a rounded face for my heroine character, as i'd like to give her more rounded and gentle features, i feel like giving her elongated features with jagged edges would make her seem evil, when i want to make her a relatively innocent character who has just gotten into a bad business. i feel like at the end if the story a rounded and softer look for her will help the audience to sympathise with her more.

so ive moved on to look at features for her - eyes, nose hair and lips. i havent done many nose and lips drawings as i feel that the face shape, hair and body is more important to look at for this project.
