I turned in the art for UY 155: The Secret of the Hell Screen, an Inspector Ishida Mystery.
The art was drawn on 11×17 inch 2-ply 500 series Strathmore cold press bristol board. The image area is 10×15 inches.
After the perspectives were determined using vanishing points, I started inking with an older Koh-i-Noor ArtPen (discontinued) filled with Badger Black Opaque ink. The older pen is broken in and has a nice flex to it, able to make thin and bold lines with the same stroke. The blacks were spotted with a Pentel Brush Pen filled with the Badger ink.
