Yellow Iris is a very tricky subject; in fact any Iris is fraught with difficulties.
You have managed to avoid any over exposure areas which is a common problem with this sort of scene.
But, more depth of focus would have looked better; however, you also need to keep the background well blurred so this is bound to be a compromise. And ideally, if possible, pick a perfect bloom next time not one which is half eaten. Possibly this was the only one available?
Having water drops on flowers is a matter of personal preference. I avoid it while some others will spray water on to petals before shooting.
