Hiya … people aren’t ignoring you, but you’re posting in a very specialist forum which is all about creating scripts for ZBrush, not basic modeling. Post questions in the Main forum and you’ll get a lot more views and help.
Anyhow, your basic problem here is that you’re using a sphere to model your head, but with the ‘pole’ of the sphere where his nose is, and you’re starting out with too many polygons. When you first select the Sphere3D tool, before you load it, go into the Initialize palette and reduce the H and V Divide sliders to a much lower level than the defaults. Turn the tool into a polymesh tool, load it, turn on X symmetry, select the Move tool and start moving points to create a basic head shape. Then increase the mesh density a step and refine the shape further. Increase the density again and keep pulling and pushing points. And so on.
Do this basic procedure again and again (and again) and, over time, you’ll get better and better. There are loads of threads in the Main and Tutorial forums to help you improve your modeling. Good luck.
