Chinese-style illustration with the artistic conception of Song Dynasty landscape, delicate ink line drawing and soft mineral pigment coloring, silver moonlight spilling and reflecting on the water, overall with light blue and celadon jade as the main tones, embellished with soft pink flower branches, hazy mist in the air, detailed flowing reflections on the river surface, supplemented by an almost imperceptible pale golden glow, cinematic and poetic lighting, ethereal Eastern aesthetics, high-end Chinese-style picture book illustration quality, 4K details. Close-up: A young woman leans by a wooden window, quietly gazing at the river flowing under the moonlight outside the window. Moonlight pours into the room through the window, softly illuminating her profile, sleeves, and the window frame, creating an intimate, subtle, and emotionally charged atmosphere. Outside the window is a wide river, sparkling, clean and bright as if washed by moonlight, extending into the distance with a slight sense of flow and layers of shimmering reflections. The image should highlight the contrast and balance between the indoor close-up of the figure and the vast moonlit river scene outside the window, conveying feelings of tranquility, longing, poetry, and emotional intimacy. Elements such as a Chinese wooden window, distant mountains, riverside pavilions, a light boat, and flower branches can be added, but the overall composition should maintain restraint, elegance, a sense of blank space, and a refined picture book aesthetic.
