A stunning, realistic mythological hybrid woman with a human upper body and a long serpent tail instead of legs, slithering powerfully across the ground. She has glowing eyes, long flowing white hair, and wears detailed warrior armor with a mystical design. She carries a large, ancient sword in one hand, ready for battle. Her skin is human from head to waist, and from the waist down it transitions into scaled snake skin. The character has a fierce, regal expression, resembling a powerful goddess from British myth. The background is a dramatic mythological setting with ancient ruins, mystical fog, and glowing lights. The camera angle is low and from the front, capturing her entire body as she moves forward, coiling and slithering with strength. The image is highly detailed, cinematic, and realistic, with dynamic lighting and a sense of divine power.
