Proportions of the head for artists

I have been learning to draw since December of 2017 it has been a really interesting journey, and there a lot of awesome things to learn, one of them is head drawing and specifically the proportions of the head, I don't want to make a really long post about it so I decided to make this animated GIF that explains the whole thing.

Plase remeber this is porportion rules do not work 100% of the time, everyone is different but at the same time similar.

I used photos from unsplash.com and animated the images with Krita.

I hope you like it
