Digitally Coloring Hand-Drawn Art & Isolating Line Work

This is a tutorial I made about some techniques I've adapted from other tutorials on how to digitally color my drawings. I like the look of hand-drawn ink illustrations, but watercolor doesn't give me the effects I want. So, I've taught myself some simple ways to add color digitally to get the look I want. 

This tutorial covers some techniques I've learned from other artists. I digitally color my handmade ink drawings using two different techniques. First is a simple multiply and paint technique. The second part of the tutorial shows how to isolate line work so that the drawing can be digitally colored without using multiply.
