**Scene:** A Christmas-themed 3×3 photo-grid collage of two young friends.
**Input:**
* Left person = Image 1 (always on the left side of the grid, called **CHAR_L**)
* Right person = Image 2 (always on the right side of the grid, called **CHAR_R**)
**Output:** One single square image containing a 3×3 grid collage (9 tiles combined into one image, not 9 separate images).
---
### 1️⃣ Face Consistency (Highest Priority – Identity Lock)
* The face of **CHAR_L** must match the person in Image 1 with very high fidelity: facial structure, face shape, eye shape, nose, mouth, skin tone, and proportions must stay the same.
* The face of **CHAR_R** must match the person in Image 2 with very high fidelity.
Hard constraints:
* No face swapping, no blended faces, no “template face.”
* No excessive beauty filters.
* Across all 9 tiles, both people must keep the *same* identity. Only expressions may change.
### 2️⃣ Layout & Overall Style
* Layout: one image that contains a 3×3 grid (9 square tiles).
* Each tile has a thin white or pale-gold decorative border.
* It is **one collage image**, not 9 separate images.
Style:
* High-detail, bright, saturated **modern Japanese Purikura (photo-booth)** style – cute and lively color palette.
* Depth of field: shallow DOF – soft bokeh background, sharp people.
* Overall: realistic portrait photography, **not** illustration / manga.
---
### 2.5️⃣ Center 3D Pop-out Visual Emphasis (Strengthened)
* The central tile is fixed at **Row 2, Column 2** (index 5), with the theme “holding hands heart pose” (see section 6).
* The two people appear **larger and closer** to the viewer than in the other 8 tiles, but still with natural full-body proportions.
3D sticker effect:
* Apply a white “sticker” outline around the **entire pair** (both people + their hand-heart gesture).
* The silhouettes of the center figures clearly **break out of the grid**: head, arms, legs, etc. can extend beyond the [2,2] tile border, partially covering the borders of the four surrounding tiles, creating a “breaking out of the frame” effect.
* Add a soft light-gold / beige drop shadow directly under the center figures on top of the grid to enhance depth and floating feeling.
* The other 8 tiles remain normal size (mostly half-body / mid-shots) and do **not** break the grid, which further emphasizes the center pop-out tile by contrast.
---
### 3️⃣ Christmas Background (Unified Across the Grid)
* Background colors: soft pastel shades such as light pink, lavender, mint green, light blue, in solid or gentle gradients.
* Christmas elements: small snowflakes, star glows, tiny hearts, Christmas tree outlines, gift box outlines, etc. scattered in the background.
* Across all 9 tiles, the background style must be consistent; small hue variations are fine, but not completely different art styles.
---
### 4️⃣ Clothing & Hair – Gender-Adaptive Christmas Rules
* No gender is assumed in advance; the model infers gender from the reference photos.
* Clothing templates change only by gender type; **left/right positions never change** (Image 1 always left, Image 2 always right).
#### 👗 Female Outfit Template F_A (Cute Santa Style)
* Main colors: red or wine-red Christmas dress, or top + skirt set.
* White faux-fur trim on neckline / cuffs / hem; optional bows and lace decorations.
* Hair: keep original hairstyle; you may add small Christmas hair accessories such as red ribbons, bells, fluffy clips, mini wreaths.
* Optional small gold or pearl jewelry.
#### 👗 Female Outfit Template F_B (Japanese Lady-like Christmas Style)
* Colors: red, white, and green combinations, e.g.
* red knit top + plaid skirt,
* green sweater + white skirt, etc.
* Fabrics: wool, knit, or other warm winter textures.
* Hair: keep original, plus subtle Christmas hair accessories.
#### 🧣 Male Outfit Template M (Christmas Casual / Semi-Formal)
* Top: Christmas-colored sweater (red / green / navy), possibly with snowflake or Nordic geometric patterns;
or red / dark-green Christmas jacket / blazer.
* Underlayer: shirt or simple turtleneck.
* Bottom: dark long trousers.
* Optional low-key scarf.
* Hair: keep original hairstyle.
#### Gender Combinations
* **Two females:**
* CHAR_L → Template F_A (cute Santa dress).
* CHAR_R → Template F_B (Japanese lady-like Christmas outfit).
* **One male, one female:**
* Female → Template F_A.
* Male → Template M.
* Left/right positions remain fixed (Image 1 always left, Image 2 always right).
* **Two males:**
* CHAR_L and CHAR_R both wear Template M.
* Different sweater or scarf colors can distinguish them and create a “Christmas brothers / buddies” feeling.
* **Hard clothing rules:**
* No pajamas, loungewear, T-shirt + jeans everyday outfits.
* No overly revealing or non-Christmas outfits.
* Outfit style must be exactly the same across all 9 tiles; only folds and perspective may change with the pose.

### 6️⃣ 9 Grid Poses (Center = Full-Body 3D Hand-Heart)
Overall expression: energetic, playful, a bit cheeky, clearly close friends.
#### Row 1
1. **Hair Grab Heart (1,1):**
One person playfully grabs their own hair; the other makes a finger-heart gesture. Both smile at the camera.
2. **Double-Hand Big Heart (1,2):**
Both use their hands together in the middle to form a big heart shape, with bright, happy smiles.
3. **Crossed-Arms Cheek Pinch (1,3):**
Both cross their arms; one person (or both) gently pinch the other’s cheeks. Slight close-up; cute and fun.
#### Row 2
4. **Crossed-Arms Overhead Heart (2,1):**
Both cross their arms, then use one hand above their heads to form a heart, together forming a big heart, full of laughter.
5. **Hand-Holding Heart (2,2 – Center 3D Full-Body Breakout):**
* Full-body shot of both characters, from head to shoes.
* They hold each other’s hands; with the free hand, each makes half a heart so that together they form one complete heart in the center.
* Soft, sweet smiles; they may look at the camera or at each other.
* Figures are slightly larger and pushed forward; apply white sticker outline around the pair; silhouettes break out of the [2,2] grid borders, partially covering surrounding four tiles.
* Add a soft shadow under the figures to create a clear 3D “pop-out” effect.
6. **Pinky-Promise + Finger Heart (2,3):**
One does a “pinky promise” gesture, the other does a finger-heart. Warm, playful expressions. Normal grid tile (no pop-out).
#### Row 3
7. **Crossed-Arms Pout / Tsundere (3,1):**
Both cross their arms, make slightly exaggerated pouting or “fake angry / tsundere” faces, but obviously trying not to laugh.
8. **Hand-Holding Cheek-Heart (3,2):**
They hold hands; with the other hand each draws a heart shape next to their own cheek. Expression cute and charming.
9. **Crossed-Arms Single-Hand Heart Close-Up (3,3):**
Both cross arms and each makes a small finger-heart with one hand. Camera slightly zoomed in, more face-focused; confident smiles.

### 7️⃣ Christmas Decorations (0–2 per Tile)
* Lightly and randomly add small elements such as snowflakes, stars, light spots, Christmas tree line art, gift box line art, bells, bows, candy canes, little hearts, etc.
* Decorations should be light and airy, in neon / hand-drawn line-art style.
* They must **not** overpower the image and must **not** cover faces or hand gestures.
* Around the central 3D hand-heart foreground, decorations can be slightly richer, but still must not cover faces or hands.
---
### 8️⃣ Text Decorations (Edges Only, Short Phrases)
You may add a small amount of short neon hand-written style text at the edges of individual tiles or around the overall collage:
* “Merry Christmas”
* “Xmas”
* “Happy Holidays”
* “2025”
* “Besties” etc.
Text must avoid faces and key hand poses; no logos, watermarks, or long advertising sentences.
---
### 9️⃣ Final Hard Constraints
* Only these two people may appear in the image; **no third person**.
* Clothing, background style, color tone, and lighting must remain highly consistent across the entire 3×3 grid.
* No unrelated text, brand logos, random numbers, or watermarks.
* Faces must match the reference photos closely; only expressions may change, not identity or facial structure.
* Output must be **one single 3×3 grid collage image** (with the center being the 3D full-body hand-heart foreground), not 9 separate images.
