How do you approach drawing different age groups (child, adult, elderly) in a comic art style face?

Children typically have larger heads relative to their bodies, rounder faces, and larger eyes. Adult faces have more defined features and proportions. Elderly faces show wrinkles, sagging skin, and potentially smaller eyes. The key is to subtly adjust proportions and add details to convey age. For example, a child's jawline will be less defined, while an elderly character's will be more prominent with skin folds.
