1. Characters can be analyzed and categorized based on their functions within a story, as proposed by Vladimir Propp who identified 7 common character types including the hero, villain, donor, and helper.
2. Character design should take into account the targeted age group, with simpler designs for young children and designs that allow for growth and self-reflection for older children.
3. Workshops are proposed for designing characters incorporating elements, transitional objects, attributes, and themes to teach character design concepts.
