A quick test playing about with the Interactive Grooming in Xgen for maya.
I took a base human hand model & gave it a quick sculpt in Zbrush , took it back to maya and put a basic rig in to pose the fingers . Painted it up in substance painter quickly and applied some Vray shaders .
The leaves are just some maps quickly applied to basic poly planes with alphas & DOF applied to the cam
It's just a quick test, I spent only a couple evenings to get a feel for the IGS.
