Héros de science-fiction stoïque en tunique bleue et dorée ornée

a striking, vintage storybook illustration, retrohippie, a kind of dirty urban illustration, with a strong sense of scientific adventure. This style is a clear blend of European sci-fi and fantasy illustration, in the vein of Jean Moebius Giraud of a stoic, middle-aged Caucasian man with short, dishevelled platinum hair and a determined expression, wearing a dark blue, high-collared tunic with intricate gold ornate detailing across the chest and shoulders. He is fitted with a dark orange eye visor that covers his left eye, featuring a prominent red lens with a wire extending downwards. A large, circular emblem with a red 'A’ insignia within a golden, highly decorative circular frame is centered on his chest, connected by ornate gold straps and chains. The background features a large, circular window or architectural element with geometric patterns and ornate detailing, rendered in muted gold and blue tones. The lighting is dramatic, casting strong shadows that highlight the facial features and the textured fabrics of his attire. The style is a blend of comic book illustration and a classic, almost medieval aesthetic, conveying a sense of power and history. The perspective is a medium shot, focusing on the upper body and face, with a slightly low angle looking up at the subject. The overall mood is serious and heroic, with a touch of mystery, style is reminiscent of Jean Moebius Giraud illustrations
