i give my opnion :
Helen was a great performer.
Vasilisa is a "normal" girl and she is not shy but she is not there to provide "shows". I appreciate that.
Regina and Sher are not shy and are "good" girls. Just Give them each their room, kick out Polya and request them to be more present in the apartment and they will be perfects
Violetta : Ok she did not fit RLC project
