Good evening,

@ RJC: I would agree with tuschcarsten that it could be a version problem. Which version are you using? After allot of people now can start the plugins I think this is the onliest possibility left.

@ grimber: I had problems to understand what you wanted me to change. This it what I read out of it: You want me to change the arrangement of the leaves, right? What I could change is the angle, i.e. a randomly alternating. The other thing that also could be done is to add another face, or more, to a branch or trunk. But this would raise the vertice and triangle number..
I think this forum could be a good base to discuss this changes. As long as the creator keeps simple and the models low-poly, I am opened for changes. But I need more than one opinion on that..
Greetings
André W.
