Terrifying humanoid monster in a dark abandoned environment

A terrifying original monster, never seen before, standing in a dark and eerie environment. The creature has a distorted humanoid shape, with elongated limbs, twisted posture, and unnatural proportions. Its skin is pale, cracked, and partially decayed, with veins visible and subtle glowing underneath. Its face is deeply unsettling: hollow eyes emitting a faint eerie light, a wide unnatural grin filled with sharp irregular teeth, and subtle asymmetry that creates discomfort. The monster is positioned in a cinematic horror setting: an abandoned place (such as a foggy forest, ruined hospital, or decaying building), surrounded by darkness, mist, and shadows. The atmosphere is heavy, tense, and suffocating. Use dramatic lighting with strong contrast, dim backlight, and soft fog diffusion to enhance the fear factor. Ultra-realistic, highly detailed textures (skin pores, dirt, scars, wet surfaces), 8K resolution, cinematic composition, depth of field, volumetric lighting, horror movie poster style, dark color grading, sharp focus on the creature, film grain, realistic shadows, unsettling mood, masterpiece quality.
