Really neat shot, only minor nitpick is that I would prefer the front petals to be in focus rather than the rear flowers while keeping the center in focus, just a minor nitpick, this is a fabulous idea and an incredible job with it, very well done.
Back to comment and bump: I orginally gave this a 5, as my definition of centered was dead center both horizontal and vertical. Taking a second look, you did a really nice job with the shallow focus and the lighting. The only suggestion I have for improvement would be to include the ladies eyes in the image. It would have really strengthened the connection between the flower and the lady for me. Bumping to a 7.
Great composition with a superb backdrop. The focus is just a tad too shallow as it really needs to include the front pedals seeing as how that is really what your subject is. Incredible eye for photography though. Well done!
