Transform the subject into a fierce medieval female warrior, holding a sword, wearing a full set of steel armor, with long flowing dark brown hair, holding a sword in both hands, standing in front of a roaring waterfall. Her expression is firm and powerful, and her blue eyes are piercing. The wind blows through her long hair and cape, and the water splashes against a dramatic background. She strikes a fighting stance and moves smoothly. Cinematic fantasy scenes, highly detailed armor designs, epic action shots, medieval heroines, powerful female knights, fantasy concept art, and dramatic lighting.
