Face labels and useful observations

I am unsure whether face shape terminology helps listeners picture a portrait. I volunteer with a community exhibition and am drafting short descriptions for visitors. The current draft describes posture and expression before mentioning the outline of the face. My terminology notes include a resource about face shapes but a category alone may communicate less than a concrete description of proportions. I want a concise script that makes no connection between facial outline and personal character. The wording should separate visible details in the portrait from the writer’s interpretation. The final recording will be heard without the accompanying written notes, so each term needs to earn its place. I would ask a listener to explain what they pictured after hearing the sentence, then revise any wording that created a more specific impression than the portrait supports. What editing test would help identify a label that listeners can comfortably do without?
