I'm there with photogoddess..
My last shoot, I spent an evening with the *client* ( two good friends.. ) determining the "style" of the shoot we were going to do, and what kind ouf outfits ect we were going to use. We went through about 10-15 magazine that they, and I, had lying around, and made a scrap book of the kind of shots they liked, and also, the kind of lighting I liked.
Made it a lot easier to have a theme to the day without blundering my way through it.
I was also sent a link the other week to a pdf that has about 200 small photos on it ( same girl) doing 200 different poses. You could just point the the picture you wanted the model to pose like - or - I gave the whole sheet to my friend while I was setting up the lighting, and she had a look through it, which gave her ideas. This way, it was her that also felt in control of the posing rather than me just directing her, and it made the shoot flow a lot easier.
Ahh - here is is :

( yes, it's a little on the *standard* style, but atleast it gives you something to work with )
