head proportions

dont like this one too much, but if you're a complete beginner you can start there. A better way to understand a faces proportions is the loomis method this is a good tutorial. the original book is here
applying it to different people by Proko
a nice quick summary of the loomis and reilly methods and the asaro head is this video
when you dont want to use loomis there are alternatives. It's also good to check out different approaches from time to time!
here's the reilly method explained in detail
