How does your media product represent particular social groups?

In our opening scene we had two characters represented in two different ways.

The First character we have is a girl called Sandra and she is the mysterious person in our film. She seems aloof and quite mentally unstable. The personality she has seems very different. On the phone conversation, she seems like a nice person who just wants to get a house to live in. However the way she looks on screen seems like she is someone that will commit bad things. In a normal social group she could be classified as someone who is some sort of issues and have a split personality. We keep her face hiding in order to create a sense a mystery around her. 

The second character was alexia, which seems to be nice person and have no issues. She dresses in a business suit, and this suggests that she is a hardworking person who is working in some sort of business. she seems very mature and doesn't seem very frightened of the other person.
