i have modeled a head and now i am wanting to know what is a good way to start making the body by extruding the neck
Well, I think that the easiest way is to start build a body with a cylinder, matching it up to the reference. After you got the body done, just connect it with the neck.
It is simple way to get the basic body shape. Extruding from neck can be very confusing, at least for me 
ok, thanks for the help
