I had a few people ask me what I use to do my illustrations. I didn't go to art school. I don't really know what I'm doing. And I use real basic tools to do my drawings. I like mechanical pens to do the light linework as I don't have to sharpen them and they erase pretty easily. I love having a brush to sweep away the eraser pieces. And my main line pen is a Micron 05, occasionally an 08 to color in some gaps, and a good ol Sharpie for big fill ins.
