I really liked what you were going for (your instincts) - and what you wound up with! The tones of color in the bg are really beautiful and the relationship of that "softness" to the blur of the wings...as well. I would consider a couple of things to try out on this. One, bringing up the shadows or the darkest tones of the bird slightly. Also, if this was cropped, maybe "reframing" image - everything as is, but with a little more on the left side, and a fractional amount on the bottom...so that the bird eye is in center of frame horiz. and a little more of the lower left flower is showing.
That you are thinking about the backgrounds and what is happening (sometimes a myriad of things) when they go out of focus is great. As an aside, I saw this image of a Mamba a few days back - just stunning - especially with the lens shallow depth of field effects on the shapes/color/highlights...surrounding the head. http://photography.nationalgeographic.com/photography/photo-of-the-day/mamba-cameroon-klum/
