Another Zsketch today.  I tried using the primitives this time, a cylinder to start with. Then used a masking technique along with the Layer brush to help build up the well defined forms easily and all at the same level.  I also used flatten and pinch to help define the angles and shapes better.  He's still lumpy, but I just ran out of patience on tweaking out the details.  I kind of like the lumpy sculpey look he has right now though.

***UPDATE***

Tiki-Topo 

I successfully retopologized the Tiki head tonight.  It wasn't as much as a pain as I was expecting.  I had hear that the retopology features in Zbrush were difficult to use but I think it depends on your approach.  I could see what the topology should be with this guy pretty easy so maybe that helped too.  If you have to do a lot of editing to your new topology while you were creating it in Zbrush I can see how it could become a frustrating experience.  If thats the case then it could be easier to start by drawing the edgeloops on the surface first as a texture perhaps.  I'll have to try that in the future.  Anyway, this does mark one more step in my quest to learn Zbrush.
