That looks good ADP. The bump or normals you have look a bit too granular, in other words someone who has a sandy complexion,  but that's a taste preference thing. I'm curious if you've had any luck with displacement maps in Superfly? I ask because I wonder if it would be useful for Superfly users if included with a distribution. Not anything ridiculous, just maps baked from 2 or 3 levels of subdivision...
