夏季母婴天空拼贴画

Create a bright square 3×3 photo-collage grid showing a cheerful summer mother-and-baby outing against a vivid cloudless blue sky, like low-angle vacation snapshots enhanced with playful hand-drawn doodles. Use {argument name="adult subject" default="a young mother"} wearing a flowing white summer dress, straw sun hat, black sandals, and a large woven straw shoulder bag, and {argument name="child subject" default="a baby/toddler"} wearing a cream short-sleeve top and striped shorts. Keep faces softly anonymized/blurred while preserving natural body poses and photorealistic lighting. Canvas is square, divided into exactly nine equal tiles with thin white gutters. Tile 1: mother holding the child at hip level, both seen from below, with white handwritten “Hi~”, small flowers, radiating lines, and a pink tulip doodle. Tile 2: mother alone waving one arm high under the sun, dress and hair moving, straw bag on shoulder, with “Hi~”, smiley face, dashed heart trail, and pink flower doodle. Tile 3: child lifted into the air by two adult hands from below, feet toward camera, with hearts and white radiating lines. Tile 4: mother jumping or kicking one leg up in her white dress, straw bag swinging, with hearts, curved motion marks, and a yellow flower. Tile 5: close mother-and-child selfie-style low-angle shot, mother reaching a hand toward the lens, child beside her, with “Hi~”, hearts, pink flower, and white dash doodles. Tile 6: mother leaning diagonally into frame in hat and white dress, woven bag visible, with white hearts, radiating marks, and simple flower doodles. Tile 7: close low-angle shot of the child sitting with shoe soles prominent near the lens, add a large white smiley face drawn on one sole, plus “Hi~”, smiley, pink flower, and curved line doodles around the sky. Tile 8: mother in profile walking or turning, white dress flowing dramatically, straw bag on shoulder, with pink flower, sparkles, circles, and wavy line doodles. Tile 9: mother spreading both arms wide joyfully, dress flowing, straw bag visible, with “Hi~”, dashed swoosh arrow, hearts, and a yellow flower. Visual style: crisp photorealistic smartphone summer photos, saturated azure sky, strong sunlight, airy white clothing, warm straw textures, whimsical white marker doodles with occasional pink and yellow flowers. {argument name="doodle text" default="Hi~"} should appear in multiple tiles in casual handwritten lettering. Constraints: exactly 9 panels, no extra panels, no borders beyond thin white grid lines, no logos or watermarks, no realistic facial details.
