Elle Fanning in a prehistoric era, a lone woman embodies the stone age, draped in a rugged loin cloth, hair wild and unkempt, adorned with primitive tribal tattoos. She clutches a spear, standing inside a shadowy cave. Her eyes betray a frightened yet fierce determination. Rendered in ultra-realistic imagery, 8k resolution, infused with the fantastical essence reminiscent of Boris Vallejo and Frank Frazetta, capturing the raw, untamed spirit of survival in a long-lost world.
