How can comic artists effectively convey a wide range of emotions through facial expressions?

Effectively conveying emotions involves exaggerating key facial features such as eyebrows, eyes, and mouth. Eyebrows can arch for surprise, furrow for anger, or lower for sadness. Eyes can widen for fear, narrow for suspicion, or sparkle for joy. The mouth's shape, from a wide grin to a tight grimace, is also vital. Small details like wrinkles, sweat, or tears further amplify expressions. Consistency in a character's 'default' expression makes emotional shifts more impactful.
