I am helping edit a beginner illustration glossary, and we disagree about how much detail belongs in the face outline section. One draft lists category names without explaining the observations behind them, while another gives so much detail that the distinctions disappear. A reference about
determining face shape might help us decide which observations belong in each entry. Perhaps each entry could start with the overall proportions, followed by a separate sentence about the jaw and forehead outline. Readers could then compare the entries using the same features instead of treating one striking detail as a complete definition. I think the glossary should acknowledge mixed features, with a short note allowing readers to describe an outline between categories. The accompanying drawings could share a scale and a plain outline, keeping hairstyle details from obscuring the features being discussed. We want neutral descriptions that support observation, without presenting a particular outline as the standard that every portrait should follow. Which details are essential in a beginner glossary, and which would you move into a separate explanation with more examples?
