I am absolutely in the minority but happy to go along with the crowd since variety is the spice of life - but personally I am not a fan of the multiple girls scenes.
In your backstage shots I can see one girl - Mina K - who I can't get enough of - but in this new series she will be having to share the screen with a lot of other girls and wont get much screen time.... ho hum
Would be good if you could shoot a "bonus material" one on one with each of them before they go back home!!
