Póster: Expedición de auroras

An arctic expedition poster dominated by a sweeping aurora borealis, centered layout with a lone explorer in a red parka standing on a snow ridge with a telescope and backpack, seen from behind at a small scale against the vast emerald and violet sky, a silhouette of pine trees and a frozen lake below, shooting stars and snowflakes filling the upper space. Bold wide sans-serif headline in icy white reads 'NORTHERN LIGHTS' with a thin tracking-heavy sub-line 'EXPEDITION 2026' and coordinates printed at the bottom corner. Palette of deep teal, emerald green, electric violet and snow white. Printed on frosty matte paper with a soft-touch coating and subtle holographic flecks. The poster hangs on a wooden cabin wall beside a fur coat and an old lantern. Cool blue evening light from the upper right, arctic dusk quality, soft rim light on the paper, gentle shadow down-left. Wide shot, eye-level view, fine snow and star detail, 4k
