This would make a cool square crop, I think. I agree with the others, nice processing. The background is very soft and wispy. I just discovered that if you sit really close to the monitor, it gets even better, heh.
I've only recently come to appreciate this style of flower-shot as a category of it's own, unique to photographers. The intimate macro of a small flower in beautiful natural light. It's easy to overlook Hosta flowers but they are really nice. This shot is lovely.
