A painting of a cave with a large opening in the middle

eerie and terrifying， underwater scene:1.5， in the style of Cthulhu. The dark ocean water is filled with disturbing images that are barely visible. A massive portal appears in the middle of the scene, seemingly leading to an unknown world. Enormous and bizarre creatures are swimming in the water, their shapes and outlines indistinct, evoking feelings of terror. The entire scene is suffused with a sense of suffocation, and seems to be conveying a terrible message. (((best quality))),(((ultra detailed))),(((masterpiece))),illustration, --auto
