Elle Fanning in a prehistoric setting, embodying a Stone Age woman, sporting a weathered loin cloth and disheveled hair, adorned with intricate tribal tattoos. She grips a spear with determination, her eyes wide with a cautious, fearful expression. Set against the backdrop of a dimly lit cave, the scene captures ultra-realistic detail, enhanced by 8k resolution and a touch of surreal charm rendered through the Unreal Engine. The imagery echoes the artistic styles of Boris Vallejo and Frank Frazetta, blending realism with mythic fantasy, emphasizing her vulnerable yet fierce presence.
