Reine celte avec cheval blanc sous un coucher de soleil doré et orageux

Cinematic vertical shot, epic series finale composition. Consistent character design: A striking Celtic queen in her late 20s. She has very long, straight, light blonde hair with distinct shimmering golden highlights. Her facial features are sharp and elegant: high cheekbones, a refined nose, and intense, piercing eyes. She always wears a thick, ornate golden Bronze Age torc necklace around her neck and dark, textured tribal leather garments. Rhiannon standing proudly on a rolling green hill, next to her majestic white horse. In the background, the ancient standing stones (menhires) are silhouetted against a dramatic, stormy sunset sky with rays of golden light breaking through the dark clouds. She is looking toward the horizon, ready for her destiny. Epic, majestic, high contrast, 8k resolution, photorealistic dark fantasy style. --ar 9:16
