I have a real soft spot for youth music programs, but even in spite of that high marks for this image. Each subject is genuinely involved in their song and that adds SO much to an image, the authenticity of the moment. The oversized clothing adds much character to the image and story. In spite of the lighting, you've managed to gather depth to the shot, no small feat in this type of situation. Well done.

those girls look like they borrowed those dresses! They're all so huge on them, but at least the taller girl knows how to iron!
anyway..that was my first observation.
Relevant, of course!

very nice photo when it comes to composition and technique but i miss a "punch"

Technicaly, a nice shot that fits with the theme, but to my humble opinion, it misses something that catch immediately the eye

This is a familiar scene to me and probably to most parents who fully participated in their children's school (and/or church) activities. Nice shot.
