I usually start by drawing a circle. Then build from there. I’ll add the eyes and then the mouth. Generally I have a rough idea but tend to just wing it as I go.
The question I get asked most is what kind of pens do I draw with. For all of my outlines I use papermate pens. For the larger black areas I use KRINK markers as well as sharpies. For smaller details I will use Microns and for the white details and highlights I go with Molotow. These are just the pens I’ve learned works best for me. You don’t need anything fancy you just need to draw every day.
One of my favorite cartoons growing up was Ren & Stimpy. As a kid I couldn’t believe that cartoons could be so gross. I was in love ever since. I really enjoy the way they do those still shots that are extremely detailed and disgusting. The angles they use are what adds to the strange feeling you get when you watch it.
