Very nice. I like that you decided to leave the imperfections on the petals. I think your choice of DOF makes the photo. My only suggestion would be (for next time) not to overlap the flowers if at all possible just a personal preference, though.
Far be it from me to contradict Invisible (he has a great eye), but I like the overlapping in this photo. I think it adds to the realness of the situation rather than seeming obviously composed. Great shot
