Cell-shade Tutorial Thingy

There're already bazillion similar tutorial in DA, I know, but I just kinda want to try making one, so... _{I admit that "save your work" part is stupid too, but pffffft, oh well.... ;w;}
And mine definitely isn't the rightest one, but at least I'm sharing my experience. If there's anything you want to ask about this, just comment here, I'll answer it as best as I can

And since it's my first tutorial, I'm sure there'll be a lot of flaws here and there, any feedback is highly appreciated. also I'd love to see your artwork that was done with the help of this tutorial!
