Storyboard - Horror Scene - School Project

On this storyboard exercise I had to create an horror ambiance where a girl has to join her friends calling her on the phone. 
We had to invent the plot twist at the end on our own. 
The setting had to be a forest at night and we actually studied real storyboard techniques to show it’s night only using grayscales. 
So the plot twist at the end is that the girl is joining the wrong people at the camp, her real friends are actually the vampires so she’s actually on the side of « the bad guys ».
