hey this thread brings back memories - my first head was this tutorial too
check the monster links on the following page for my 'attempt':
https://www.flash-fx.net/old_3D_css.html

as already mentioned try the joan of arc tutorial (the tutorial I did after the head one) as it'll help get some skills in blocking out a basic body form. The head also gives you some good results.

good luck on this one as this ones quite a hard head shape to get.
