tidy and clean up of image -- 2

Hello I have scanned PDF file of a hand painted black and white image. It was originally painted with ink and pen. I need it cleaned up and contoured out so it is an outline only without the white background. I would like all the background mess cleared off. I still want the image to look handpainted so the brush strokes are important. In the picture there is one leaf that is heavy on the black and it stands out from the rest. I would like this cleaned a bit with some more white showing through between each of the petals of the leaf.
