A totally engaging combination of shallow DOF, HDR techniques, and the way you caught the light on the subject. I'm not normally a floral fan, and this is a common subject, but exceptionally well done. I think I am faving it.
The HDR isn't really noticable in this. But I amke a commitment to try and give posetive feedback even when the photo doesnt exactly meet the challenge description... I like the textures a lot, but the photo just isnt very interesting. The background needs to be filled with something, maybe a lake, of a river setting. And I'd use a photo editing program to add some dynamics to the lighting, that's a bit flat as well.
