Y2K Photo Booth Collage

Based on the user-uploaded {argument name="Number of photos" default="1-2"} clear real photo of the person, generate a vertical 2×2 four-grid photo {argument name="style" default="Y2K"} photo photo collage.

[Character Consistency]
Strictly preserve the true identity features of the person in the photo, including face shape, facial proportions, eyes, nose, lips, skin tone, sense of age, hairstyle basics, and overall temperament. The four small pictures must clearly show the same person or pair. Don't become a stranger, don't become an internet celebrity, don't overdo skin smoothing, don't use AI fake faces.

[Display Format]
Generate vertical 2×2 quadrilateral collage.  
Each frame is a standalone selfie with a wide-angle fisheye lens, with the camera close to the person. The face, arms, and spatial perspective are slightly exaggerated, but the features must not be distorted.  
There can be narrow white or candy-colored dividers between the four compartments. No black borders, no black vignettes, no round fisheye black frames, no film black frames.

[Overall Style]
Y2K photo sticker machine, fisheye selfies, trendy profile pictures, colorful flash, low-definition CCD digital camera texture, cute doodle stickers, and retro internet selfie aesthetics.  
The overall photography feels authentic; don't make it look like an illustration.

[Styling]
Please redesign your character to {argument name="character design" default="Y2K Sweet Cool"} style.  
You can add colorful camisoles, cropped knitwear, printed T-shirts, baseball jackets, plaid shirts, denim elements, transparent jelly sunglasses, colorful hair clips, earrings, necklaces, bows, sequin makeup, colored eyeliner, and more.
Clothing colors can include highly saturated candy colors such as mint green, lemon yellow, electric blue, cherry red, silver, orange-pink, and lavender purple.

[Background]
The background is designed to create a rich Y2K photo booth space, not just a single pink bedroom.
You can add elements such as colorful photo booths, neon signs, CD walls, silver mirror walls, colorful bead curtains, instant photo walls, vintage arcade machines, transparent inflatable sofas, candy-colored storage cabinets, star string lights, small disco balls, sequin curtains, colorful balloons, and more.
The overall color scheme is bright, shiny, vintage, and cute.

[Four-Grid Movement]
The expressions, poses, distances, and angles of the four pictures all differ.
Panel 1: The person approaches the fisheye shot, making a surprised mouth opening, pouting, or making a funny face.  
Second frame: The person extends their hand close to the camera, with a glance, wave, or palm close to the frame, with a slight enlarged fisheye on the hand.  
Third panel: The person is facing the camera, with a playful expression, able to wink, puff out cheeks, raise eyebrows, or laugh heartily.  
Fourth panel: Characters turn back to smile, look sideways at the camera, hold up props, or make exaggerated snapshot poses.

If it's a two-person photo, make sure the two interact realistically, such as getting close to the camera, making funny faces together, making heart gestures, getting close, or one in the foreground and the other in the background.

[Stickers and Text]
Add a moderate amount of Y2K stickers and hand-drawn elements, but don't cover the face.
Stickers can include: cherries, stars, lightning, bows, smiling faces, CDs, kitten paws, aliens, pixel hearts, transparent bubbles, colored arrows, glitter, and hand-drawn graffiti lines.
You can add a small amount of colored bubble text or handwritten sticker text, for example:
“LOVE BUG”  
“BEEP BEEP ♡”  
“PARTY MODE”  
“XOXO”  
“OMG US”  
“TOO CUTE!”  
“PHOTO BOOTH DATE”
Text placed on edges or corners looks like real sticker stickers, bright colors, slight glow and glitter texture, not covering the face.

[Image Quality]
Direct flash, low-definition CCD digital camera texture, slight digital noise, slight chromatic dispersion, slight motion blur, highly saturated candy colors, preserving the skin's true texture.  
The final effect looks like 2000s photo sticker bursts, Y2K internet avatars, and cute, quirky selfie collages.
