Single illustration, Franco-Belgian bande dessinée thriller cover vibe, semi-realistic draftsmanship, crisp inked outlines with controlled line weight, detailed cold-weather gear and ship hardware, a massive icebreaker pushing through pressure ridges at dusk, pale sun halo behind low clouds, blue-gray fog drifting across the deck, a small team of researchers in parkas and headlamps clustered near an open hatch, one person kneeling to examine a strange scratched symbol on frosted metal, cinematic wide angle, strong depth with foreground railing and midground figures, high-contrast lighting: headlamp cones cutting the mist, cold ambient light, restrained palette (steel blue, slate gray, desaturated teal, dirty white ice) with a single warm accent (sodium-orange deck light), realistic textures: ice crust, wet steel, windblown snow, subtle film grain, ominous mood, tension and mystery, no text
