In my opinion, especially evident in the second image...you're letting the color temperature of the spotlights on the actors, go too yellow. If this is how it looked to your eyes and you like how it looks...and your clients like it too, then by all means, keep doing it this way. I've only shot school and church plays in the past, but to me it always looked better to bring the color temperature closer to neutral in post, even if it didn't look like that to my eye during shooting. Your eyes/brain, at a live event, can forgive and allow for a lot...that later on...eyes looking at a printed photo, or even one displayed on the web, don't care for as much. At least that's how it's been for me. Overall it looks like you're doing fine...maybe a slightly lower to the stage perspective? I know it's easy for me to say...though! Nice job overall!
