Step 1: Things You Will Need.
sharpies or micron markers
Step 2: Pensil Drawing
Step 3: Ink It
Pointers: Grab the marker close to the tip. Make long lines and try not to stop between points. Remember you're tracing it, but you do not have to make every line fit perfectly.
Erase all the pencil lines after you let the ink dry.
Step 4: Add Some Color...
Me I like colored pencils, so that is what I used.
I like to start with a base color and add splashes here and there. Then overlap colors for certain effects. I like blues for fingers, around the eyes and around the mouth because it looks alittle like the characture is cyanotic. And green because it looks kinda moldy or toxic waste colored. Experiment, if you play with the concept then you can get all kinds of effects.
