I don’t concur. I believe you are talking more of graphic style, while I’m talking more about the worldbuilding, the ambiance, the conceptual, pre-steampunk visual language. While Shuiten is a sort of Ligne Claire extremist, I find Moebius very difficult, if not impossible, to classify. He is often called Ligne Claire, but his style is often very gritty, and his protrayal of movement is clearly inspired by Franquin, the master of movement. Moebius has such an ability to move between styles, while keeping his personality, that makes him very difficult to classify.
