ok i made this ugly looking golbin guy, from a sphere(be easy on me… its my first project in zbrush)
but i dont really know what to do next :S
i am totaly stuck!
of cause i would like to finnish the head of before i start working on the body, but i dont really know, what to do? :o
also when i finnished the face, and want to make a body for him (using zspheres) how do i put them together?
hope you can help me out!
in advance: Thanks 
You can use SubTools to append the body to the head.
It looks like you made a common mistake with the head, in that you have subdivided too soon. The best way to work is to stay at each subdivision level as long as you can, focusing on the structure to take that as far as you can go with the current polygon count. Then you divide and refine. Of course, the advantage to ZBrush is that you’re not stuck. You can return to any level at any time and work on it some more. That would be a good place for you to begin.
Be sure to check out the links in my signature.
yea i know, i subdevide way to much, but its like the smooth tool (you know when pressing the shift key) doesnt work right, when its not smoothed… it just makes a big hole :S and changing Z intensity doesnt help 
also with the mouth… i dont know how to really make it!
should i just make a big hole, and make the teeth as a sub-tool thingy?
