Nice! I like the way you've made it not very sharp, but distinct enough that we focus on the essense of the butterfly, and not on its details. The overexposed bright parts on the left wing also work well for me in that they are bright beyond reality - a hint of the other side of existence, perhaps? There are a lot of little details that I can pick up (the tilt of the branch, the OOF dark and light areas in the space at the left), that in themselves are not very significant, but together, they make the image work, at least for me. Well seen, and well photographed.
