Oriental Fantasy Game Poster

Aspect ratio: 21:9. Maintain the 3D CG rendering style of a high-finish Oriental ancient fantasy game promotional poster. Colors: low-saturation blue, white, gray-green, and wood brown. Lighting: soft warm courtyard light. Fine depth of field and layered foreground texture. The protagonist is a {argument name="character gender" default="female"} located at the upper-middle right, with {argument name="hairstyle" default="half-tied silver-black hair and a light blue flower crown"}. She has a slightly round face, eyes slightly downcast looking at a bird to the left, and a faint smile. She wears {argument name="clothing" default="misty blue and ivory silk long robe"} with layered skirts and metallic accents, sitting on a high wooden railing. On the left is a blue-gray bird on a cherry blossom branch. The background is a semi-open water pavilion with a tea set, bonsai, and greenery. Focus is sharp on the face, bell ornament, and hands, while cherry petals and foreground leaves are softly blurred. Include calligraphic titles at the bottom left and a vertical stamp at the top right. Maintain a gentle, ethereal, spring romantic atmosphere with a flowing diagonal composition.
