Facial thirds and drawing conventions
Some familiar facial proportions come from artistic conventions. Their history does not make them universal targets.
Distinguish a convention from evidence
Equal divisions can help an artist construct a face. That is different from a study establishing a representative range or a personal benefit from changing a proportion.
Photographs introduce another layer
Landmark placement and perspective affect a calculated division. Hairline visibility, expression, and framing can also complicate interpretation.
Read without ranking
Use a proportion as descriptive context when it is relevant. A difference from a drawing convention is not a defect and does not establish a need for intervention.
