The extremely narrow depth of field is a problem - not even the whole stamen is in focus. Sometimes selective focus macro can be interesting, but that usually works when the whole frame is filled by the flower. The other problem is that the background to the left of the flower is very distracting. Macro work on flowers is tough, and I haven't done a lot of work in this area, but there are people on this forum who have and perhaps they can give better advice on how they would have approached this particular subject.
