Summer Watermelon Doodle Photo Collage

Goal: Create a playful summer lifestyle photo collage featuring {argument name="character description" default="a young woman with short dark hair wearing a blue-and-white striped sleeveless top and light shorts"} enjoying watermelon in a sunny park, decorated with hand-drawn white doodles and casual handwritten English words.

Canvas: Wide horizontal 16:9 image, arranged as an exact 3 by 3 grid of 9 equal rectangular photo panels with thin white borders between panels. Use soft natural daylight, fresh green grass, shallow depth of field, and a bright airy summer color palette.

Layout and panel count: Include exactly 9 panels:
1. Top-left: the woman sits cross-legged on grass holding a large watermelon slice in front of her face, with a white fence and cloudy sky in the background; doodles include a smiley face, short rays, the word “Hi!”, and small splash marks.
2. Top-center: close-up still life of several watermelon slices on a plate or tray beside an orange bag; doodles include a crown-like squiggle, sparkle marks, and the handwritten word “Sweet!”.
3. Top-right: side view of the woman sitting on grass, smiling toward or holding a watermelon slice near her mouth; doodles include “Hello!”, quotation marks, a swirl line, and a heart.
4. Middle-left: close-up portrait crop of the woman holding a small fork or skewer with a tiny watermelon cube; doodles include radiating marks and a large question mark.
5. Middle-center: close-up of the woman holding a watermelon slice near her mouth, face mostly centered and partially obscured by the fruit; doodles include dotted lines, a heart, and a small smiley face.
6. Middle-right: the woman sits on grass holding a watermelon slice up to her face; orange bag nearby; doodles include “Nice Day!”, a wavy underline, quotation marks, short grass strokes, and small sparkle lines.
7. Bottom-left: wider overhead-leaning shot of the woman reclining or sitting on a picnic cloth on grass with watermelon and orange bag; doodles include a curved arrow, smiley face, small hearts, and motion marks.
8. Bottom-center: tight portrait crop of the woman holding an orange hat or orange bag close to her chest or face, with soft grass background; doodles include small hearts, a curved white stroke, and a large number-like squiggle.
9. Bottom-right: overhead shot of the woman lying or reclining on grass with one arm raised, orange bag beside her, and a watermelon slice near her hand; doodles include a speech bubble saying “Yummy!”, small dash marks, and a heart outline.

Subject details: The subject should appear cheerful, relaxed, and candid, like a summer picnic travel-photo shoot. Keep the face softly anonymized or blurred, while preserving the pose, hair silhouette, outfit, and body language. Use {argument name="main prop" default="fresh red watermelon slices with black seeds"} as the recurring prop in multiple panels, and include {argument name="accent accessory" default="a bright orange tote bag or sun hat"} in several panels.

Visual style: Realistic photography, soft film-like tones, slightly overexposed summer highlights, green park setting, casual social-media collage aesthetic. Add white hand-drawn doodles as if sketched with a marker on top of the photos: hearts, arrows, smiley faces, sparkles, squiggles, quotation marks, and short handwritten words.

Text content: Use exactly these visible handwritten English words across the collage: {argument name="greeting text" default="Hi!"}, “Sweet!”, “Hello!”, “Nice Day!”, and “Yummy!”. Keep the lettering informal, white, and doodle-like.

Constraints: Maintain the exact 9-panel grid, thin white dividers, no extra panels, no watermark, no app interface, no captions outside the collage, and avoid adding additional readable words beyond the specified doodle text.
