So after hours of watching tuts on how to get around the interface of zbrush. I managed to import my face from my mortal engines project and i had a little go at sculpting over it which didn't turn out too well.
Kinda didn't feel it looked like me much. So i decide today to work from just z spheres and build my head up from there which i find look far more convincing. Only problem is is that i don't know how to model the eyes in. I need to work on how to do eyes as i haven't clue at the moment.
