I would correct you, as between April 23rd an May 3rd, i saw her
Shirinkina only performed the final movement in Symphony in C on the final night gala of the International Mariinsky festival on April 1 plus on April 29 there was a gala for students where she danced the Vainonen Nutcracker pas with Fillip Stepin and she had no problems with balance.
I would like you to clarify what you saw her dance in April since she danced one movement at the beginning and one pas at the end.
Apr 27th-in Divertisment at Concert hall, Paquita - very not impressive,
Gala for students Apr 29th noon - she danced the Vainonen Nutcracker - she Failed all balances, was very sloppy with turns and fell into Stepin once (I think it was landing on a knee) - i sat on the 7th row center orchestra no obstruction to the view.
Jewels - she might have danced as well (I didn't buy that program, but 99% certain, as i saw Fateev congratulating her at stage door afterwards. She's a sweetest person and nice dancer who's been promoted too fast and too unjustifiable for her own good
