Not sure how many my other threads u guys have seen, but they've been very intensive head building lessons. I found the speediest technique to be start with a cube, proportioned roughly for ur head. one extrude downwards to give the jawline, one more to give urself the start of the neck. Then poly smooth it with just one sud division. gives a nice form to start from.

Then its just split poly and finding where those lines can run with minimum fuss.

I'll post a wire of the head when i get a chance, its not perfect. far too heavy around the nose for one.

And again thanks for the interest!
