I found this surfing around yesterday. I’d say its an intermediate level tutorial. Its in Lightwave but if you mainly follow the pictures it should translate just fine to Blender.

Have fun!

Oh yeah. BTW, the way shows how to model the face is quite good and would translate to hires nicely.
It looks like a nice indepth tutorial. Thanks for the link TorQ!
