First dabbles in Zbrush

Hello everyone, hope you all are doing great! OK, don't laugh. I've decided to start teaching myself Zbrush(well with help of some training dvds) I haven't gotten so far into the dvd yet, just introductions to some basics, I'll work along side whenever they introduce something new. So far this is my first model/tool or whatever they call it, only like 3 hours in. Just from a sphere, no zspheres or bone armatures yet though. It's um...a Martian Manhunter/Piccolo/Spock person?
