The most fun about a photo shoot is experimenting with new poses, lighting, etc. As this expecting mother to be was fixing her hair, I saw a triangle being created with her left hand. Immediately I thought, "let's create another triangle with the other hand!"
After she placed her right hand on the small of her back I wanted her right leg extended to continue making beautiful angles. So I said, "pretend like you're doing a maternity moonwalk.." Immediately she knew what I was going for and bent her leg perfectly!
