Use case: illustration-story.
Generate ONE finished, standalone portrait children's picture-book page, page 1 of a four-page family story for parent-child shared reading. This is an original fictional family, no real person references.
Artwork: polished, warm hand-painted watercolor/gouache children's book illustration, subtle fine paper grain, light brush contours, soft natural afternoon sunlight. Muted cream, sage, apricot, warm brown. Clear simple scene, emotionally tender, no all-over yellow cast, no plastic 3D look.
Recurring child DOU: about two years old, small round face, warm brown almond-shaped eyes, tiny nose and mouth, rosy soft cheeks, BLACK chin-length rounded bob haircut with short straight full bangs, no hair accessory. APRICOT sleeveless pinafore dress over CREAM long-sleeved shirt, SAGE short socks, no shoes. Natural toddler proportions.
Room: warm oak floor, low SAGE sofa on LEFT, closed pale PEACH front door on RIGHT, ivory oval rug in center. Only these simple anchors, uncluttered, no toys or other people.
This page's action: the little girl sits on the sage sofa at the left, both hands naturally resting near her knees, quietly looking toward the CLOSED door with a gentle expression of missing her father. Daddy is NOT visible yet. One child only, anatomically coherent, two arms and legs, no duplicate limbs.
Page design: portrait 2:3 or close supported portrait ratio. Full warm watercolor illustration in upper roughly 78%, soft transition into a clean ivory caption area in bottom roughly 22%. Preserve roomy margins. Caption should be large, sharp, readable, dark warm brown, centered. Chinese top line, English second line. No title, no page number, no speech bubble, no extra lettering, no watermark. Render exactly these two lines:
爸爸，我想你啦。
Daddy, I miss you.
This first page establishes the exact child identity, clothes, room and artwork style for all remaining pages. Make it beautiful enough for a real finished family picture book.
