I just noticed that the Bump Normal is not connected to the TranslucentBsdf Normal, that should be corrected.  Upon looking over this shader, there is a connection that I have a problem with.  The TranslucentBsdf should be connected to an AddClosure node but in this setup, that node is connected to a MixClosure node.  I need to examine this closely and, perhaps, tweak this a little.

Let me know what you think and if it will be useful for you.
