Personally, I'm not too great at artistic shots like this. That being said - this is a great photo. It's refreshing to me and I think that comes with the cleanliness of the background and the harsh flash-like lighting that you've got going on. The detail of all the little florets is striking and I really appreciate that the light was harsh enough to illuminate almost all of the shadows in that area of the photo.
One suggestion I can offer is that my eyes keep wanting to look at the petals that are out of focus. Which I suppose is intentional. But it kind of follows a golden ratio line and that could be why! Just some food for thought but you clearly know what you're doing!
