Revisions-Changing the Mother's Character

After meeting with my co-director, we have decided to change the role of the mother to a sister or friend instead. One of the critiques we received from our class after showing our film was that the role of the mother was unclear because the actress was young and the script does not explicitly state her to be the mother. My co-director and I decided to revise the part by making the actress look older with makeup, but we realized that since all the actors we're using are our peers, it is just too difficult to make the mother look older. We think it will be easier to keep her role unclear as to who she is, but it can be assumed that they have some sort of relation to each other.
