Example Concept: To effectively convey emotion in character expressions, consider the relationship between facial features and emotional states. The eyebrows can indicate surprise or anger by their position and angle, while the eyes can convey sadness or joy through their openness and the presence of tears or sparkle. The mouth's shape, whether a frown, smile, or grimace, further defines the emotion. Exaggeration of these features can enhance the emotional impact, making the expression more readable and engaging.
