とある廃屋にて

A horrifying cosmic horror creature clinging to the ceiling of a ruined Western-style mansion, seen from the perspective of someone standing at the top of a grand staircase and looking upward. The creature is massive and spider-like, with eight long legs ending in humanoid hands with sharp hooked claws. Its head has no eyes, but a translucent skull reveals its exposed brain. Its mouth is filled with huge, sharp fangs. The creature fills the dark vaulted ceiling space, lurking in shadows. The only light source is the faint flicker of candlelight from below, casting eerie, dancing shadows that partially illuminate the monster. The composition emphasizes the horror of discovering the entity just above, hidden in the darkness until it is too late. Style: cinematic gothic horror, cosmic horror, ultra detailed, low-key lighting, moody ambience, 4K.
