When tackling a crowd scene, the trick is to define the space first, and then determine the spaces where the people in the crowd will fill. In this case, I knew the round tables would create a regular pattern I could use to place the students. But first, I needed to define the perspective of the room. Using Sketchup, I generated a simple model of the cafeteria, lined up a camera angle to match my initial drawing, and pasted simple renders into the first two panels.
