Thinking of an old oc: concept

This is just a basic concept sketch of Coal. I was thinking of him being more of an upperclass type of pirate and decided on a long overcoat, tucked-in shirt, belted trousers, and knee high boots. His mouth was sewn shut while he was alive when he was just a messenger-boy. A couple of drunk teens thought it funny to sew his mouth shut so he couldn't eat, drink, or talk. He later died of dehydration because no one would help him. He became a member of the undead and searched for a porpoise in death. Adventure and exploration became his passion in death. Traversing through the many dimensions on the run from the inter-dimential PD and making both friends and enimies along the way.
