Begin with pressures, not appearance. State the character’s age range, work or social role, environment, daily physical demands, resources, and the contradiction that creates tension. An urban rescue engineer must move through water, carry equipment, remain visible, protect notes, and communicate under stress. A night archivist needs access, close inspection, storage, and quiet mobility. These facts create clothing, posture, wear, and props that a reader can interpret without a paragraph of biography.
Separate enduring facts from the current scene. Body proportions, face structure, hair construction, handedness, baseline posture, and core clothing belong to the model. Wet fabric, a damaged sleeve, formal attire, fatigue, or a bandage belongs to a state. Record state changes with the story timeline so an injury or missing prop does not appear and vanish accidentally. A generator can suggest either category, but only the production bible decides which version is approved.
Avoid building identity from shorthand stereotypes. Occupation, disability, culture, age, body type, gender expression, and class affect design, but they do not prescribe one face, posture, or costume. Research real material and involve informed reviewers when the representation carries weight. Give each person agency, functional choices, and context rather than using visual difference as an exotic decoration or automatic sign of virtue, danger, intelligence, or poverty.
