Aurora Valley Nature Film Poster

Design a digital movie poster for a nature documentary, formatted in a 16:9 landscape ratio for a nature photo essay. Show a broad alpine valley at blue hour, with a clear river leading from the foreground toward snowcapped peaks and a sweeping green aurora. Use a low riverside viewpoint, placing smooth stones and grasses in the foreground while mist layers the distant slopes. Choose natural cyan, pine green, slate, and subtle warm gray. Preserve photographic realism with fine water texture, atmospheric depth, delicate grain, and balanced exposure. Leave a calm section of sky for documentary title typography. The image should feel tranquil, expansive, and scientifically respectful, with no logos or watermarks.
