Sophie and her friend created multiple cuts of a trailer for their film project, getting feedback from friends and classmates at each stage. They added elements like a newspaper report and an "obsession wall" to make the plot clearer. Feedback helped them realize the dialogue was too long and it seemed more like a film opening than a trailer. For their poster and magazine cover, they received feedback that helped improve the colors, text, and photos to better convey the thriller genre. Getting input from their target age range of 15-21 proved very useful at each stage of the process.
