This is so lovely! Great image. I think it's quite successful. The only critiques I have are:
I wish that the edge of the second flower was in the picture. I think it looks a tad cut off.
I also would darken the leaves of the completely blurred flower in the background and blur the leaf in the bottom left hand corner to reduce distraction.
Overall though, it's a beautiful image and I adore the way the light is coming through the petals. It's quite divine. I love this angle you chose, it really shows off the not often seen details. I love the way the colors of the petals compliment the blue in the background. I would try to tone the browner parts of the background into that teal, but perhaps not since it really draws the eye to the focal point. Your focus is superb as well.
