Doing some exercises. The bald guy was inspired by an old Batou sketch I posted on my FB in 2016. I drew Batou with this really large jaw and short nose. Keeping that in mind, I did a quick ink sketch (the one at the bottom) of the bald guy---except that he turned out to have "good" eyes. The character's supposed to be a tough guy with a bad history.
So, I did another quick sketch (this time in digital) and fixed the eyes and chin a bit to give him that look (line work placed on gray with white highlights).
