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