Anyone read "Lord of the Flies"? To speak a person had to possess the conch shell. Reminds me of when I was working on a group animated project. Instead of budget for a content management software to control who animated what character in which scene, we just used a conch shell.
This thing was quite the enigma to sketch. Wishing I had decided some other medium. Something dry and not wet. Though, the shell does come from water. It's a sketch and I cheated a bit in rendering. Didn't keep enough white out for certain areas. Started light enough that it was easy to go darker if I had to. Still there's a lack of pop from certain areas.
