Anya - I am not a Li fan but I must say he is the closest thing to the legendary Njinsky. I have seen old films of Njinski and what made him so 'great' was his BALLON . I'm not sure if I spelled that correctly, it is pronounced bal lone. It means the ability to pause in the air before completing the jump, or as I would say 'hang' in the air. It's a natural thing and something one can not work on.
Another example would be Dorothy Hamil's axel. She competes the revolutins in the air, before coming down for a landing. Other skaters will complete the revolutions as they are descending before the landing. Just my imlpressions.
