it's an overwhelming shot. but two things kept my attention:the phenomenal and brilliant lighting paired with the fall of the curtain. both things make this shot lively such as you're sitting next to the model watching the scene in real life.
I like the lighting here, but it's a bit hot on her backside, making her appear thinner than she is. If you shot this in RAW, you might try some recovery there. Also, the colors in the middle are fantastic, but the top looks like fake vignetting, giving them a muddy appearance.
