Some other users have complained about the specularity set too high with the EZSkin shaders; that is also my assessment so I tone down the specularity on the Blinn node.  The image below is a converted skin texture from V4 to Dawn with EZSkin applied.  I have been tweaking the shaders with the texture to some satisfaction.  Some shaders got completely reworked like the eyes and the teeth.  I've also been experimenting with layers and tattoos.
