Tutorial - Lineart Process

This is the first tutorial I've ever made! I suck at explaining things

So many people asks how did I got these "sharp thick" lines and I decided to answer them by making this tutorial!

I'm pretty sure this tutorial can also work with Photshop,Manga Studio and all that but for now this tutorial is for Paint Tool Sai users

Also,should I make more tutorials in the future?
