Affiche d'une Famille dans une Grotte de Glace Antique

A cinematic vertical movie poster featuring [a family of four and their golden retriever] standing inside [a massive, ancient ice cave]. Towering translucent blue glacier crystal formations shape the walls and ceiling, illuminated by bright daylight filtering from above. Etched into large ice pillars are glowing white runic symbols such as [suns, triangles, and wavy lines]. On the left foreground, [a golden retriever] sits looking upward, beside [a young woman with long brown hair in a patterned knit sweater and dark jeans], hands in her pockets gazing up. Behind her stands [a bearded man wearing a black beanie and heavy winter jacket]. On the right, [a boy in a grey beanie and puffer jacket and a girl in a cream beanie and scarf] look up in wonder. Delicate snowflakes drift through the air, catching the light. Cool blue, white, and icy grey palette contrasted by warm tones in the dog's coat and the sweater.
