8k ultra-high definition, 写实oc rendering, high-end cg texture, depth of field effect. an ancient-style female general stands on a city wall under a full moon. her cool white skin exudes a delicate luster, with her cheeks and armor outlined by moonlight in soft contours. her long black hair is tied into a high ponytail with a silver ribbon, and a few strands flutter in the wind. she has sharp phoenix eyes, bold eyebrows, and her lips are pressed tightly. she wears silver-white light armor engraved with cloud and crane patterns, with a dark blue battle robe underneath, and a sword hangs from a navy blue belt around her waist. the battle flag flutters behind her, and distant torches blur into golden bokeh. in a low-angle medium shot, she turns slightly sideways, one hand on the hilt of her sword and the other behind her back. the blue-silver color scheme highlights her cold and heroic aura.
