I'm on Day 2 of taking the free Pixar in a Box classes on Khan Academy (link below) and I wanted to share some key takeaways for character design:
External features:
Is your character a human, animal, object?
What kind of clothing do they wear?
How does your character move?
What's the first thing you'd notice when looking at them from a distance?
Internal features:
What do they like to do?
What do they fear?
What emotion do they most often feel?
How would they respond if trapped in an elevator?
