The theme is supposed to be the princesses during a negative turning point in their life even though not all the princesses suits the theme, in Ariel's case it's a positive turning point, but in that case the negative in that is that the cosequences of it are overall negative

Jasmine's isn't much of a turning point, but considering she's not the main character of her movie it's sort of a negative turning point

Elsa's isn't the most negative turning point, it later turns out to be a postive turning point, but based on just this scene it's a little negative turning point, also I hadn't made an icon of her from this scene
