A lone figure resembling Elle Fanning stands in a prehistoric landscape, surrounded by ancient caves. Her wild, tangled hair cascades down her shoulders, partly obscuring tribal tattoos etched into her sun-kissed skin. Dressed in a tattered loin cloth, she clutches a primitive spear with white-knuckled intensity, her eyes wide and fearful as she scans her surroundings. The scene is rendered in ultra-realistic 8k detail, capturing every nuance of her expression and environment. The atmosphere is steeped in the rich, dynamic style of Boris Vallejo and Frank Frazetta, merging vivid colors with dramatic shadows to evoke a sense of visceral, timeless adventure.
