Terrifying full-body image of an alien creature resembling a humanoid spider, with venom dripping from its fanged mouth as it crawls out of a shadowy cave. Its glowing green eyes are menacing, set against a nightmarish backdrop. The creature's skin is a tapestry of intricate patterns, with sharp, angular limbs that capture the essence of horror. Bathed in dramatic, chiaroscuro lighting, its appearance is both photorealistic and cinematic. The atmosphere is intensified by subtle cinematic noise and a sense of palpable tension, portrayed in stunning 8k detail, and enhanced by a vertical aspect ratio.
