Elle Fanning in a prehistoric setting, a lone woman in the stone age dressed in a primitive loin cloth, her hair wild and untamed. She bears tribal tattoos that tell an ancient story, clutching a spear for survival. Her expression is one of heightened awareness and caution, standing at the entrance of a shadowy cave. The scene is depicted in ultra-realistic detail, capturing an 8k resolution with the meticulous artistry reminiscent of Boris Vallejo and Frank Frazetta. The environment conveys both the raw beauty and danger of this ancient world, with a focus on the intense mood and vivid textures.
