Elle Fanning in prehistoric time, a lone woman from the stone age era, clad in a simple loin cloth with untamed, wild hair adorned with tribal tattoos. She grips a weathered spear, standing in front of a rugged cave. The scene captures her intense, wary gaze, all rendered in ultra-realistic 8k detail reminiscent of the artistry of Boris Vallejo and Frank Frazetta. The atmosphere embodies an ancient world with a dynamic interplay of shadows and light, showing her as both vulnerable and fierce against the untamed wilderness.
