Elegant Hanfu Sisters Poster

Create a serene vertical cinematic poster in the style of an elegant Chinese historical drama still. The canvas is a 9:16 portrait frame with a large expanse of pale blue sky occupying the top half and two young East Asian women standing in the lower half on an ancient stone terrace. At the top center, place refined black Chinese title typography reading {argument name="title text" default="大乔 · 小乔"}, with a smaller subtitle directly underneath reading {argument name="subtitle text" default="东风不与周郎便"}. The scene should show exactly 2 women: the woman on the left wears a flowing {argument name="left robe color" default="white"} Hanfu with wide sleeves, subtle embroidered trim, long black hair in a half-up ancient hairstyle with delicate pale hair ornaments, and dangling earrings; she faces slightly right with a calm, composed expression. The woman on the right wears a flowing {argument name="right robe color" default="pale aqua blue"} Hanfu with wide sleeves and faint floral embroidery, long black hair styled half-up with pale blue ribbons and hair ornaments, and she looks slightly downward toward the left woman with a gentle reserved expression. Behind them, include an old Chinese stone bridge or palace terrace with carved railings, an ancient pavilion roof on the left, soft distant blue-gray mountains, and atmospheric haze. Use soft natural daylight, muted pastel colors, shallow depth of field, graceful composition, realistic faces, delicate fabric texture, and a quiet poetic mood. Add a small bottom-left signature mark: a blue dot followed by cursive text {argument name="signature text" default="DeepBlue"}. Avoid modern objects, extra people, harsh contrast, fantasy armor, or overly saturated colors.
