A dark and mysterious underground entrance in a dense, misty forest, autumn leaves blanketing the ground. The entrance is a concrete structure with a dark, rectangular doorway, partially hidden by the surrounding foliage. The forest is thick with tall, bare trees, their branches reaching up into the overcast sky. The light is dim and diffused, creating a sense of unease and isolation. The overall mood is eerie and unsettling. hyperrealistic rendering, detailed textures, volumetric lighting, cinematic composition, deep shadows, desaturated colors, high resolution, 8k, dramatic lighting, photorealistic, ominous atmosphere, focus stacking, shallow depth of field, film grain, muted color palette.
