I would think that the map driving translucence value should be greyscale leaves on a black background.  The transparency map should be likewise.

     I can't see what's plugged into alt specular, but it should be limited by (i.e., multiplied by) the transparency map, or you'll get highlights between leaves, making it look like clear plastic.

     Laurie, I also guess that it's for his dryad, but even so, while Vicky may have considerable thickness, the leaves would not, so I think it would be a better strategy to use translucence.
