I'd thing the idea of a mix is great...get someone like Lynn or another pro-photog to get some great stylized shots, but have some good candid shots in the mix, which can help a provider come across as more genuine. While there is no small portion of fantasy involved in providing, I believe the best providers are able to be themselves within the artificial framework of the encounter. Some beautiful, but not completely stylized pics in a showcase can help.
There's a picture in Nikki's showcase

that I think is a perfect example. It's the one where she's standing on a kitchen counter posing. The lighting isn't perfect and the whole shot is kind of random, but it really works.
Chloe's showcase, when it was up, was good example of the concept. She had some great sexy and glamorous shots by Lynn, as well as some great candids.
