For that one, I sketched from fanart as a model, then added effects and cropped out most of the sketch. I am fairly confident that there is no IP issue with Red Hook since there is no suggestion of endorsement nor is there a suggestion of it as being "The Highway Man" and wasn't modeled off any art from the actual game. The fan art that I sketched from was 3.0 CC. I don't know if a sketch of a 3.0 CC model counts as fair use or if I'm clear but I'll reach out and see how they feel about it.
