아기 흑백 하트 풍선 모노톤 화보

[Input]
- output_size: 1024x1366 (3:4 portrait)
- reference: 1 baby photo (front pose, knee-up)

[Purpose]
Convert the user's attached baby photo into a monochrome heart balloon viral Instagram portrait. The baby stands centered in a {outfit_color} tulle dress, with a cluster of {balloon_color} heart-shaped balloons floating above and a small balloon cake sculpture beside.

[Scene — image-to-image edit, preserve baby identity]
Use the attached photo as the base baby. PRESERVE the baby's identity (face proportions, age, hair style, skin tone) but RE-STYLE the scene completely.

Outfit:
- {outfit_description}
- Hair styled into two small "antenna" buns on top of head (tiny twin braids/buns standing up like antennas) — the natural baby hair is visible

Heart balloon cluster:
- {balloon_description}
- 15-20 heart-shaped foil balloons of varying sizes (mix of solid {balloon_color} and translucent clear with {balloon_color} ribbons)
- Floating ABOVE the baby's head, taking up the upper 40% of the frame
- Slight cluster overlap, dynamic floating composition

Balloon cake sculpture:
- {cake_description}
- To the right or left of the baby, about waist-high
- Small balloon-tied cake structure with bows

Background: pure clean off-white / soft warm white seamless backdrop. NO scene details. Subtle soft floor shadow.

[Style]
- Premium Korean studio viral Instagram portrait
- PROPS palette only — outfit, balloons, and cake are in {balloon_color}-and-white tones
- SKIN is NATURAL warm color (do NOT desaturate skin) — preserve baby's natural skin tone, rosy cheeks, lip color
- This is a COLOR photo with monochrome styling on props, NOT a grayscale-filtered photo
- Soft warm daylight, gentle subtle film grain
- Editorial / fashion-baby vibe

[Composition]
- 3:4 portrait
- Heart balloon cluster upper 40%
- Baby in middle 40%, standing centered
- Balloon cake sculpture in lower-right (or lower-left), waist-high
- Plenty of off-white breathing room

[CRITICAL — Preserve baby identity]
- Face proportions, age, skin tone must clearly match the attached photo
- Hair re-styled into twin antenna buns (using the baby's actual hair, not a wig)
- Outfit is re-designed (tulle dress)

[🚫 PROHIBITED]
- Grayscale-filtering the baby's skin (skin must keep natural warm tone)
- Any color outside {balloon_color}-and-white on OUTFIT/BALLOONS/CAKE (skin is exempt — natural skin color)
- Cluttered background
- Photorealistic harsh details — keep editorial soft tone
- Brand logos on the dress or balloons
- Text overlay
