Well for example if you had a cow girl in new york that wouldn´t work unless she is new to the city...if you had a famous person in the 1600´s she would not be dressed like katy perry or kim exc.
I would say yes.
This is because of the name itself -- a "group" project. It's not a "solo" or an "alone" project. You are responsible for the other people's work in your group. It is important to make sure everyone contributes their own work in a group project, and not someone else's.
Best of luck
