A Young Cellist at Orchestra Rehearsal

A young cellist visiting our orchestra. I went to the hall floor (the stage is about 1 m higher than audience floor) and shot this from there. The problem here was I had to catch a moment when there was not too much movement, but still have some action. G1 is not as its best in indoor action shots without flash. Flash was not an option as it would have disturbed the rehearsal concentration - usually in most live concerts flash usage is not permitted.
