I really like the lighting and processing Peter. And of the three poses I prefer the first followed by the third. I would prefer the hand / arm to be lower on the first though as the large, flatter area of aluminium tends to draw the eye too much I think. It works better in the other two but I like the shapes etc of the first pose best an it has a more thoughtful and natural feel to it.
Not really. I find the pose a little forced whereas the first has a natural balance to it. Maybe if it was a little more dynamic, maybe moving from one 'pose' to another.
I love the concept and the images you produced. A bit dark, but overall very nice captures. I rather like #2, though I think the hair curling around to under her arm is a touch distracting. Job well done to me.
