should i submit some of the animation ive done?
You can but their primary concern is that you can draw the figure. This isn’t a program that will teach you how to draw. They’re looking for people who can already draw. This is a program that will teach you how to take your drawing skills and animate with them. Some of my classmates already experimented with animation prior to attending; some of us (myself included) had never animated before starting this program. So you can include some of your animation in your portfolio but it’s not going to make or break the situation.
