Create a vertical cinematic poster in a refined Chinese historical costume drama style. Show two elegant young women standing side by side on an ancient stone terrace, framed from about mid-thigh upward, with a soft misty mountain range and traditional Chinese pavilion architecture in the background. The left woman wears a flowing white hanfu with subtle embroidered trim, long wide sleeves, a black half-up hairstyle with pale jade hair ornaments and delicate dangling earrings; she faces slightly right with a calm, reserved expression. The right woman wears a pale aqua-blue hanfu with embroidered sleeve details, long wide sleeves, a similar black half-up hairstyle with pale blue ribbons and hair ornaments; she looks gently downward toward the left woman with a serene expression. Use natural daylight, cool blue-gray tones, shallow depth of field, soft haze, realistic skin, graceful posture, and a quiet poetic atmosphere. Add centered Chinese title text near the top reading {argument name="main title" default="大乔·小乔"} in elegant black calligraphy-like serif type, with a smaller subtitle below reading {argument name="subtitle" default="东风不与周郎便"}. Leave a large expanse of pale sky above the figures for the typography. Add a small bottom-left signature mark consisting of one blue dot and the handwritten text {argument name="signature" default="DeepBlue"}. Vertical 9:16 composition, photorealistic, delicate ancient Chinese aesthetics, no extra people, no modern objects, no watermark beyond the signature.
