Ultra-wide skull wall with lone figure AI Image Prompt

Ultra-wide-angle deep vertical two-part composition, overcast sky with dense clouds, low-saturation cold gray tones, cinematic lighting, UE5 global physical illumination, 8K hyper-detailed realism, delicate surreal oil painting texture, no plastic AI rendering feel, lonely wilderness epic, megastructure aesthetics. Upper half: a massive wall of stacked skulls rivaling mountains, built from countless wailing skulls, extending layer by layer infinitely upward, towering into the clouds, overwhelming in scale; the wall is weathered, mottled, covered with fine cracks and moss, structurally feasible with realistic mechanics, a mild near-future primitive megastructure, no extra tech props. Lower half: open and gentle blue-green grassland dotted with small white flowers, large areas of empty negative space, a tiny lone human walking in the center of the plain, extreme size contrast between human and giant structure, highlighting human insignificance, solemn and awe-inspiring atmosphere, low-angle upward shot.
