It was VERY windy.
This was shot using a 18-70mm with a 25mm ext tube.
It is backlit; I wanted to convey a bit of the translucency of the petals. I agree that the tip is a bit underexposed, but I was more interested in the sunlight coming from the rear and didn't want to add a light source from a different direction to the flower, but chalk that up to my limited experience.
I DID use Gaussian blur on background, especially on the flower in the upper left BG.

thanks
