This was drawn with a Japanese fountain pen, Japanese ink, and painted with Japanese watercolor. To be specific - I used Holbein watercolor and Platinum Carbon Black in a Pilot Falcon. This trio is perfect for me.
Here's the sketch for my Draw Your Fear submission. Drawn with a Pilot Custom Urushi fountain pen using deAtramentis Document Ink Black.
