It's almost there, and the leafs are almost completely transparent, but I feel like the margins should be more blurry. Perhaps with further tweaking it's possible to get more out of it.
I took a quick photo for comparison. It's not pretty, but in front of the camera (lens 50mm, F4.0) there's a dry brown and a green branch and some leafs, and they are completely blurry and see-through.
