This is Stitch by Chris Sanders.

I saw someone draw with dots like this and I wanted to try it. It works surprisingly well.

I made the outline with a blue pen and then filled it out with dots creating the shadoweffect. The more dots the darker the area.

Here he is when he is done.

Bonus info: This shadowmethod hurts your hand pretty quickly.

Materials:
Blue and black pen and paper.
Balck pen was 0.2 and 0.1
