Yes there is much to be learned from Marcos!
Here's link to Malo's generalized method for modeling a character - it may be a little difficult to follow because of awkward language (non-native English speaker, but eons ahead of me in expertise). The illustrations are terrific.
I've already done your head using Malo's method. I will post, even tho my result is not as smooth as I would like, or that Malo or Marcos, or Will, or many others etc etc would do. I have to go out shortly, so will post screen shots later to show the steps using his method (maybe 18-20 steps).
I can't wait to see it.
