Brief from client...
We want to create a collection with a character that will resemble the seven deadly sins. He'll have distinctive features on his face and body to show the resemblance to each sin, and on top of that, he'll have different traits in layers for clothes (upper body & shoulders), head (hair & hats), eyes, and mouth, with around 100 traits in total. Let me know your thoughts, and here's several references.
This is my initial sketch for client.
