Use vertex modelling, there is no better way to do it, I also find it easier if you have a reference image of a human head, and then model it from that, use the nose as a map of how to do the face, a human nose splits the face in half, so try modelling only one half of the head, starting from the nose and go out, after that side is done, select it (use face select) go to edit>duplicate selection, then you need to flatten it so go to edit>vertex>flatten, click the axis you want it flattend on, then go to edit>vertex>weld to make a head a whole object, I used this process and made the following...
Vertex manipulation is the way to go, never ever use box extrusion when making an organic model, it just doesn't work! I use vertex modelling for everything now!
Guns arn't the problem, people are the problem, shoot all the people and guns arn't a problem anymore.
