All I have to say about the Youth Grand Prix is that it is exremely badly organizes.
When one of the participant chose, after looking at the list of the repertoire suggested, a variation pay for a costume and hour of coaching, you cannot go to her after and tell her that she cannot use the solo chosen because of problems with copyrights.
The girl choose to dance "Sylvia" solo from the pas de deux choreographed by Balanchine, just as it is suggested on the list of the repertoire :

Then she reads on her evaluation "wrong Choreography" then told that she couldn't use Balanchine Choreography because of the right problem with the Trust. Well it unadmissible to do that to a young student, that of course was distressed and confuse and needed a lot of guidance after that, without talking about the money spent on a costume and long hour of training.
If the dirgeant of the competiton knew about that ( by the way "Sylvia" is still a choice on the site) they should have noticed all the dancer that decided to dance that choreography or tell them to get the right or to simply find another solo to dance.
