You know, I might be wrong, but his multicoloured eyes give me the feeling that he's going through some great internal conflict. Could it be represenative for that? I know eyes always are a pretty big point in defining characters; for instance, my character, Maxwell Knox, an old ghost from Victor's past, has soulless steel-blue eyes, while my other character, Alex, has rich choclate eyes to represent her down-to-earth simplicity and "dudeness".
Yes, you are correct. I actually designed him that way many years ago even before he had a story and he eventually "grew" into his design. In short, he joined a gang when he was a kid but when he leaves it, things get complicated. He eventually finds out who his real friends are and his old and new lives keep clashing.
