Process GIF nsfw reward (Patreon)

Here is a process gif of that January nsfw reward  ( ͡° ͜ʖ ͡°) 

As you can see at some point I had to draw head models to figure out the head position, (one of them was changed after all cuz I didn't like it) and it made me wander if anyone would be interested in some head modeling study to help guide you when head is being "attacked" by perspective and foreshortening?

 edt: I was notified that gifs are not working from mobile and while I'm trying to find out how to fix it I'll post all the steps as separate images
