Generate a 4:5 vertical high-completion creative character poster, themed "Open Her Dream / OPEN HER DREAM". 

The overall style is a high-precision paper-cut pop-up book style poster, where the screen looks like an opened pop-up paper art book, with a dreamy star-moon fairy tale world unfolding in the center of the pages. The overall image is not an ordinary illustration, but an art exhibition visual that combines paper-cut layered texture, exquisite character expression, and complete poster layout.

The main subject is a young adult Oriental female, visual age about 20–26 years old, with an overall dreamy, romantic, quiet, and ethereal temperament. The facial features are cool and light-toned + dreamy and exquisite, the face shape is a small oval or exquisite melon seed face, the facial contours are delicate and smooth, the jawline is clean, the eye shape is slender and soft, the gaze is quiet and gentle with a bit of dreaminess, the nose shape is elegant, and the lip shape is natural and soft. The character has black long hair naturally flowing, with a slight wind-blown feel, the hair is smooth and elegant, and features a small amount of starlight hair accessories or small shimmering embellishments.

The character's figure is well-proportioned and graceful, highlighting the lines of the shoulders, neck, collarbones, arms, and the movement of the skirt. The clothing is a moon-white light gauze dress, with transparent fine gauze shoulder wraps, the overall dress unfolds layer by layer like paper-cut moonlight petals, the fabric is light and transparent, with a small amount of light gold and starlight silver detail embellishments. The hem of the skirt has a clear large-area sense of flow and layering, as if gently spinning open in a star-moon dream.

The character's pose is: standing in the center of the opened pop-up book, body slightly turned to the side, head looking back at the camera, one hand naturally placed lightly near the chest or collarbone, the other hand naturally hanging down and slightly extending backward, the overall pose is elegant, restrained, and graceful, with a slight sense of looking back and the temperament of a dream world protagonist.

Background / Concept direction: A star-moon fairy tale world unfolds from the opened paper-cut pop-up book, the image is constructed around the character with elements such as a huge moon, paper-cut clouds, golden stars, arches, flying birds, exquisite paper-cut castles, and a blue dream sky. Behind the character is a huge arched structure and a central moon; the moon should be large and exquisite, with delicate engravings and a sense of paper art; floating or hanging star decorations surround it; the castle is located in the area behind the character to the right, rich in layers but not stealing the spotlight from the protagonist. The bottom must retain the structure of an opened book, with pages unfolding layer by layer and naturally connecting to the dream world above.

Overall color palette: Moon white + fog blue + light gold + starlight silver. Maintain a light-colored dreamy night sky feel, do not darken it, and do not make it a deep night black series. The lighting atmosphere is a dreamy soft-focus light + moonlight-style paper art display light, overall bright, soft, transparent, and exquisite, with a slight sense of moonlight shining and a high-end paper art exhibition light feel.
