Daly, the character with the dreads, is the best buddy character we meet in Episode 0. He is supposed to be Afro-Latino. Sly and Daly bond over being the only minorities in their tiny rural town in Colorado. They also share the fact that they are both from broken families.
Below them is a sketch of Sly as a teenager sporting a pompadour which was probably cool back then..
And below that is a picture of Anca's hair after she does an under shave in episode 1. I guess you could say I like giving each of my characters a unique hairstyle that speaks to their personality.
