Elle Fanning as a prehistoric woman, set in the Stone Age, adorned with a loin cloth, her hair wild and untamed, featuring intricate tribal tattoos. She grips a spear tightly, standing in a shadowy cave. The scene is ultra-realistic, rendered in 8k resolution with an unreal engine quality. Her expression is one of fear and determination, captured in the legendary styles of Boris Vallejo and Frank Frazetta.
