Very nice technique; exposure and composition spot on. Working the theatrical/stage lighting to your advantage. Timing is everything on this sort of shoot, and you've got that nailed.
There will be highs, and there will be lows. It's the persistent few who fly in the face of adversity, who conquer the difficult task. When you no longer recognize adversity is when you triumph and prevail.
Best of luck, but luck favors the prepared (Louis Pasteur-ish).
