The Grim Adventures of Billy and Mandy was one of my favorite shows growing up. I always wondered what they would look like when they got older. One of the projects in my character refinement class gave me the perfect opportunity to explore that a bit.
I tried several body types on Billy but decided it was best for him to be big and muscular. I did this because I had the idea that Billy would grow up to be a bully and the only person that could keep him under control would be Mandy.
