Well I wouldn't use nurbs for modeling this, so no I wouldn't use Kurt's methode.
the most common way people model heads/humans/humanoids is via polygons and further tweaking with sub-d's. There are tons of head-modeling tutorials out there, have a search on google.

I wouldn't recommend trying to model this particular image really, certainley if you are just starting out with modeling.
You might want to sketch out a front/side view of your charahter and start from there, model the character/gun etc..
Rig the charachter and pose her the way you want.

So sorry to burst the bubble here, but you have a very looong way ahead of you if you want to model this image from skratch.. Good luck

edit: gender issue :p
