The Calarts portfolio has been expanded a bit since I applied—in my year, the only part that was REALLY required was the figure drawing/observational drawing section. I did include a sketchbook of mine alongside it, though, as well as my weird little animations* I did in highschool.
I did happen to get in straight from highschool, but that isn’t traditionally where most Calarts students come from. A lot of the time they prefer older students who have a stronger grasp on time management and self-motivation, which are not as common among people who have only just graduated highschool. :\ In any event, good luck re-applying!!
*I really wouldn’t recommend scrambling to learn how to animate just so you can apply to Calarts or a similar animation school—even now I don’t think they REALLY take animation skills into consideration for applications, and doing animation on your own can be a very stressful and, potentially, not very rewarding process using time that would be much better spent working on your observational drawings or sketches.
