Creating translucent exoskeleton material

I’m working on modeling a bug and am trying to get the right material for the legs. Here’s an example of I need material wise.

Anyone have an idea on the material settings?

I have this material in my library. Maybe with some modifications…? :confused:

It looks too slimy. I want a hard semi translucent shell with a slightly irregular surface.
