Phew ! It was very long to do this tutorial but I finally did iiiiit ! This tutorial is very long because I wanted to illustrate it as much as possible. I wanted to add some tips and analyzes too.
Anyway, it's my first tutorial on DA. I did some few french tutorials when I was younger but they are quite bad (and I worked with a mouse !) so I won't submit them.
I hope it'll help you, give you ideas, inspire you or cheer you up.
For deathofrats and all my watchers.
