After you use Panel loop, the thickness is free for you to create insets in it or whatever you want. I typically use the ZModeler’s Edges-Insert and the Polygon-Qmesh-Polyloop. Once you have done this, use Group-by-Normal with the appropriate angle value to assign Polygroups to isolate where you want hard edges (considering you can add Creases where 2 Polygroups are not the same color).
By the way, I realize I should’ve put those character in this thread here, so for those you have not seen my Sinners project with my other tips, here is a link:

Here’s the finished version of the model I showed real quick at the Zbrush Summit during the Keos Masons presentation. The idea was to represent how sentient robots of the future will still celebrate the 80’s Metal culture. My idea came from the quote “The Metal will live on” from a Tenacious D song.

Wowaa! Another masterpiece of art Marco! What’s that script you are using to create turntable from jpg sequence?
Hey thanks!
It’s a Java script that scrolls between 90 rendered images. Here is more info on how to set it up:

thanks for the kind words everyone!
I was actually thinking of a wig thing made of wires or something but in the end i preferred the bald head silhouette 
Rock n roll!
At popular demand, here is a closer look at the torso part.
