All good info, Anton. Things like this fascinate me, too. A few years ago I was involved in a project to create a database of facial types; the idea was to be able to dial up any face by choosing from a list of identikit options. The work is copyright to my former employers, so I can't use any of it here, unfortunately. However, one useful thing I did take with me is the knowledge that all faces are pretty much the same, after allowances are made for skin and eye colour, weight and factors such as scars and birthmarks. Eyes are pretty much always the same size, and in the same place, lips are more or less the same, and so forth. Yes, there are differences, but they are much less than we percieve. All of which is echoed in anatomy and art reference books, which always concentrate on the "canon". A good deal of the individuality we see in a face is due more to our own perceptions than anything else, which means that creating a reasonable likeness of some real person can be doubly difficult. That said, it's also more of an interesting challenge, too.
