My female lead is 4'9 and has scars on her legs, back and shoulders. She's also cinnamon brown in complexion being Navajo and Mexican. So while there are some beauty conventions she fits (very long hair, big eyes and long lashes, rather hourglass shaped) there are lots of conventions she does not fit into.
Your character doesn't have to check every 'outside the beauty standard box' rather, they should be characters who DON'T check enough beauty standard boxes to be a Hollywood (or most animes) female lead
