Her character design is god-tier.
She's made up with so many gawky quirks: broad, mannish shoulders wider than her hips, crooked, uneven teeth with prominent gap, slightly bulbous forehead, overbite, dorky, lopsided facial expressions. And the sum of all those parts is a character that not only feels unique and rounded-out, but is really attractive in the way that real people are,with all those 'blemishes' just adding to their overall look.
The way she's animated, too, is great, with tiny details like her posture and how she shuffles daintily on her feet like a ballerina.
She could have used a bit more personality, but in a packed-out film she still comes across as charming and likeable.
