Good Form: Ono Pirouette on Bars

Nastia Liukin (USA) is known for her good form. In this Ono pirouette, she has her feet pointed and her legs straight, despite the fact that she is rotating 360 degrees on one arm! The only slight error is that while her toes are together, her ankles are a little bit apart. This would most likely not be a deduction though, since it is so small.
