Meats Miere is crazy. He actually sold me on Zbrush after I saw him do a demo at Siggraph a few years back. Anyway, something to consider reading up on is surface topology and edge loops. It's one thing to make a good looking model, but sometimes you may find if your topology is incorrect things break or do things you don't intend when you try to pose the model.
I wish I had more time to get back into Maya/Zbrush, but I'm back in school (I have a degree in 3d animation) for web development and between that and my internship I have no time. Good luck to everyone.
When I get home I'll find the link I had to some GREAT tutorial movies that start with the very concept of Zbrush and it's interface, all the way to setting up image reference planes and then on to modeling a photo realistic human skull step by step. I snagged the course material off a teacher somewhere, though I'm sure it's on youtube at this point......
An alternative to Zbrush if anyone is interested is called Mudbox. From what I hear it's a bit easier to use, Zbrush's interface is.... Cumbersome at times. Especially if you come from a more traditional 3d package. Hope to see some cool stuff here.
