After Elsa pierces Anna's heart with ice, she is shocked at her powers. I like this brief scene as it shows Elsa REALLY DOES CARE about Anna. She's just very hesitant about showing her love.
The animation in this moment is so perfect! Elsa's eyebrows go slightly up, her mouth opens, her shoulders relax, basically, her whole world just collapsed around her and she's in shock. This movie is so beautiful.
my favorite princess would have to be Elsa, even tho technically she is a QUEEN But, she is my favorite because she is a metaphor for depression of which I suffer from.
