Well, many people have been asking for a guide to drawing Invader Zim characters, so I decided to finally respond to that request! However, there's so much to cover with drawing Invader Zim characters that I decided to divide this tutorial into parts. As it says at the bottom of this tutorial, I'm open-minded to additional ideas for tutorials concerning Invader Zim drawing topics. Feel free to give your suggestions below!
However, do note that I am already planning on making tutorials for the following topics:
1. Invader Zim heads (they're so complicated, they require a tutorial of their own)
2. Advanced Character Drawing, which covers specific details of drawing the main characters, such as Gir, Gaz, Zim, Dib, and others.
3. How to Train Yourself to Draw the Invader Zim Style
