Dance skills? by Shim Jaewon SM director in charge of choreography and performance
Yuri...She tries to pursue perfection. She excels at group performance more than her solo. I like her overall movement and atmosphere. When there is a closeup shot of her, she knows what expression to make and knows how to move her body to ensure it comes out beautifully on the screen.
Yoona...I like her wave the most. Although she doesn't have a flashy solo, when she performs the same choreography within the group, she is great at being in rhythm. Because of her long arms and legs, her line is appealing. Even when she dances to a male dance routine, she still looks cool. She is able to express her dance in a natural way without over doing it. Her talent for comprehending the choreography is excellent.
Sunny...Rather than say she dances well, she is good at expressing them. When it's her part, she is able to convey her image with conviction. It's possible because she possesses the talent to express herself. And still, she is great at leading when it comes to teamwork. She also has the ability to create dance routines that is harmonizing.
