Thanks for the good class! I followed your protocol by first roughing out the character in a tiny sketch. I decided to go with Beau-- a half-Asian guy who looks like he'd eat you for lunch. We don't get a lot of mean Asian men in American media, so why not?
Then I created some interesting shapes to see his possible postures. I decided to put him in a position where he had to protect some children, and then thought that the first one looked the best, so I developed it further.
So here is the basic skeleton.
Then I added some linework for the character.
Please let me know if there is any criticism! I'd love to improve the work further.
