Anne looks great there. I do like her wavy hair (it looks quite informal) and the cat ears. I would've liked to have seen ears like that other than just at the ball. There's a certain cuteness about them, especially on Anne. Her hair as well makes it seem like she's more relaxed.
Her hair in TDKR, while lovely, has a more formal style, almost as if it has to be properly worn up and brushed back like a school girl. Here in the audition photos, it's Anne letting her hair down. Also looks more like a "just had sex" look.
