To design my character faces, I started by copying faces from an anatomy book and adding my characters’ features.
I did not like the result of this. Because I copied drawings instead of photos, the end result had a sort of uncanny valley effect. To fix this, I did some more practice sketches based on references.
To design the final iterations of the character faces, I copied photo references and added my characters’ features. I also drew the robot’s face, which was easy, because it’s a simple design I had already drawn.
Overall, I am proud of the final face sketches.
