Thanks for all the comments. The first image was taken at f2, the others at f4. In the first I was trying for sharp eyes and mouth and soft dof on the rest of her face. When you're that close at that aperture, accurate focus is pretty important. One of my regrets was chopping off her fingers in #2. I was tempted to do some cloning from other shots but instead promised to myself to be more careful in the future.

Corin was very nervous being a first timer and with 9 photographers waving cameras at her and giving her mutiple directions all at once. She handled herself quite well all things considered. My preference for next time would be less photographers at a time for a shorter period of time. So photog 1, you have 5 mins, go to it, the rest of you start planning your shots.
As I said, she was nervous and really didn't know where to look. My goal in the exercise was to get better at directing the
model and to try a combination of images looking stratght at the camera as well as some looking away. There is no doubt in my mind that the ones with the direct eye contact show a connection between the
model and the photographer and make for a more pleasant and stronger image. I also intentionally performed a lot of work on the images in photoshop to try to get the mannequin look. Again this was a learning exercise for me. I saw Corin last night to give her some prints. She'd changed her hair style and colouring and looked even more sensational. I didn't have my camera with me.

Another lesson learned.
Once again, thanks for the feedback. I learned a lot and am looking forward to the next opportunity.
Cheers
John
