Watched the video~ She did very well. Can see why she won.
Her costume looked fantastic on her, loved the personal touch of the ribbon and the gloves.
The elegance of the costume matched the music.
Excellent use of the enormous concrete dance space.
Her moves matched the music.
Her facial expression & emotion, had to look really hard to discern. The video quality is atrocious, portions of her emotion is lost in digital translation. But that is not the dancer's faulty. Got one heck of a chuckle from those expressions and emotions I could see.
