広大な未来都市でホバーボードに乗る若者

a modern stylized illustration inspired by Jean Moebius Giraud, frame of a young man on a hoverboard glides smoothly along a wide, complex futuristic massive city high above the ground. The overall mood is one of organized chaos and sci-fi innovation, captured with a medium shot perspectivec, conematic noir lighting, matte gouache texture. Gouache texture, matte finish, mid-century modern illustration, vintage cel-shading, and analog film grain, moody noir atmosphere, dynamic movements, feels like a modern graphic novel
