Astronaut Flees Spider-Crab Aliens Into Giant Maw

the prompt

Cinematic photorealistic sci-fi horror chase sequence set on a dark, foggy alien planet with rocky canyons and floating islands. An astronaut in a white and blue spacesuit runs desperately for his life through a narrow rocky path, looking back in terror. He is relentlessly chased by multiple giant menacing red spider-crab alien creatures with glowing orange eyes and sharp legs.
The camera dynamically follows from behind and switches to high-angle shots revealing the terrifying scale. The path dramatically transforms into the inside of a massive ancient monster’s mouth lined with huge teeth and fleshy walls. The astronaut keeps running straight into the giant maw as the spider monsters close in. In the climax, the enormous creature awakens, its massive head rising with jaws opening wide. The astronaut is thrown into the air as the gigantic beast emerges powerfully from the mountain-like structure.
Intense action, dramatic foggy atmosphere, realistic creature details, dynamic camera movement, high tension, and epic scale. Dark moody lighting with volumetric fog, fast-paced editing, and thrilling survival horror vibe. 13-second high-impact sequence.
