Is there a guide to the shape of the human head?

Like, um something for me to study to help me with my drawing?

Yes, there is. First, provides actual reference photos of heads (and bodies.) Second, has the Loomis anatomy and figure drawing books on-line, which also give proportions for drawing heads. Third, there’s a tutorial on heads in BlenderArtists own Community Journal (click Articles, then follow the links to the December issue Female Face Modeling tutorial).

That should be enough to get you started.

and well generally Riven Phoenix’s videos on youtube are great!

find them here

also, assuming you have a head, there is always the mirror option. Self portraits are fun :smiley:
