I know that shooting theater one does not generally have control of the lighting.  In this case, I doubt the audience is seeing  the actors any better than your photos from the wings. (shoot the lighting designer?)

Aside from the lighting problems which you can't control, I'm unsure what the impact of the photo should be.  I can't see faces and the actors don't seem that engaged in the scene.

The difficulty of theater photography is to capture something meaningful as a photo, without the context of the overall production.  This may be a "turning point" scene (in which case the director should be shot!) but as a moment in time in the production, there is just no impact we can take from it.

All of the above are not in your control.  You can't force a director to create exciting scenes, or influence lighting designers who light the stage but forget to light the actors.

Work to find scenes of interest, reaction, impact, or even action from which we can invent a story.
