IU (Lee Ji-eun) vs Scarlett Johansson

IU's facial proportions are consistently cited as near-ideal — upper, midface, and lower thirds in the golden proportion. This is her most consistently cited structural halo.

While proportionally excellent, her overall feature scale is small, which in some Western PSL frameworks rates slightly lower than larger-featured phenotypes at the same proportional quality.

Clear positive canthal tilt — one of the most-cited features in her community analysis, approximately +3–5°.

Nasal base slightly wider than ideal. Most-cited failo in community analysis.
