John, I like esp. the second, the graphic look emphasizes the delicateness of the plant structures very nicely! A nice result. But, the tree in the background doesn't add to this and reminds me that this still is a photo. This is a case where removing the tree altogether would proably make sense. Maybe then, the newly created white space would perfectly work alone, but in case not I could also imagine cloning some of the light plant structures (these between the dark black main plant parts, dont know how to say it better) to these upper areas. Hope this makes sense...
