I actually don't know what I was doing with this drawing. I kinda experimented with how to draw the lineart (I ended up using this line-drawing tool) and looked at some speedpaints. Apparently, to color the lines you use a clipping mask.

Also, I have a question!

Since I have a TON of DEH and Heathers fanart in this book, should I make two separate books for DEH and Heathers?
