I like the rim lighting on the stamens of the one flower. Very nice.
The rest seems a bit high contrast for my taste, it creates a sort of unpleasant sensation of acutance which doesn't fit well with the flower, to my way of thinking. You've got a sort of odd sensation of "razor sharp stainless steel.. flowers" in here. The composition is pretty nice, I don't much like the chopped bud either though. I think I would have gone in tighter, so emphasize the crop so as to take away the "mistake" feeling of the one cut off bud.
