I feel these are excellent both in the composition and the lighting given what you had (or didn't have!) to work with regarding the lighting, yes things could have been slightly improved here and there with fill in flash and setting up strobes, diffusers, reflectors etc but this would have turned the whole experience into a full blown, time consuming studio type shoot. Great pics - it maybe would have been nice to see some after shots with the actress on stage to put the 'behind the scene' shots into contex
