Lantern-Sentinel of the Storm

Towering lighthouse keeper rendered as a mythic urban sentinel in an art nouveau poster composition, striding across a rain-lashed neon megacity rooftop promenade with a lantern staff raised like a beacon to the storm, wrapped in wind-whipped rough burlap robes layered with ornate brass fasteners and soaked fringe, elongated silhouette and monumental posture, face stern and otherworldly beneath a high cowl, city canyons below shimmering with holographic signage and flooded reflections, sweeping decorative arcs and flowing architectural motifs framing the figure, iridescent oil-slick palette of petrol violet, acid teal, molten magenta, slick emerald, and bruised copper, rain catching prismatic highlights on every surface, colossal sense of scale and destiny, intricate poster borders, sinuous linework, dramatic upward perspective, luminous atmosphere, richly textured fabric and wet stone, epic and ceremonial, high-detail illustration, widescreen 16:9
