good ideas, just watch the "strangeness" of 2,3 some may love it others may not just keep it in mind. For 4 go farther back and get more dof in there to really emphasis her. Popular pose for wedding photogs is a shot somewhat like that, usually though to have the bride in the front groom in back
Great pics! Why is it that the female gets all the attention. I told my photographer to put me in focus and her out! Well.. that didn't work. I guess it's all about her
