I think if you have seen the introduction to Zbrush from digital tutors then the only place you will find tutorials for high resolution modeling is in your Imagination and some real photos of people's faces and some face models made by Zbrush artists out of the many forums and websites, like cgsociety.org.
If you need something more specific or anything at all, just ask
hey thnx
but i have a other prob see if you have seen the original zbrush site
there you can see the character and they are showing the tuts i was hopping to get something like those.
