Here is my first head that doesn’t look like play-doh rolled in a ball.
I know the feeling Gottsbet, lol. It does look like you are getting the shape down. keep at it. Zbrush is like anything else. You improve at it the more you use it.
Yeah, keep at it - not a bad first try. Did you start with just a sphere, or 6 Zspheres? Look around the pixologic site and the tutorials on here - full of great advice. Before you know it, you will be making heads for fun. I can just about get the head shape right, but struggle at the mo with texturing, and fine detail, but it’s a great learning process - just keep checking this forum for advice. 
Good luck!
(This was my first head, but I read a lot of posts on this site before I did it!)

I found this Tut for box modeling a head. I am going through it right now with wings3d. I know box modeling really is not zbrushish but it may help anyway.
Far better than my first serious attempt I must say.
Yes, practice and a plan that suits you is all it takes.
Just try all sorts of techniques, Box modeling was the first one I tried and it worked quite well for me but I now find Zspheres to be easier.
It’s different for everyone and you never know which technique is for you untill you’ve tried a few.
This is my 100th post and as you can see my work is far from perfect, it’s a long road but fun to walk on once you get going.
Hello Manixolated, perhaps this can help you get up to speed.

Many people seem to think th process valuable. You will have to read through all of it to get the theory and update info, but it might be of value. 
Thought I would show my lastest head I did. It is not done in zbrush, Sorry. I am looking for a good TUT on doing ears. I find myself leaning torwards box modeling. I think there are some zbrush box modelers out there. I do not own Zbrush yet and I was wondering how box modeling in Z is done and for some tuts so I can give it a wing (not wings3d) in the Z demo.
You’ve probably already seen this and it doesn’t deal with head modeling specificly but it’s a great tut for box modeling in Zbrush.

Also when you get Zbrush you can look in the help section, it has a great script that shows how to do box modeling step by step, very easy to follow.
Jason Belec thanx, I’ve actually been following you’r thread for awile now and it has helped me allot.
Thanks Manixolated, I have not seen this. Will give it a shot.
