Retro Heisei Purikura Photo Strip

Generate a Heisei-era retro style of these characters making expression. Create a vertical 4-panel layout with expression in every frame. Include different expressions in each frame, with a slightly overexposed flash effect, nostalgic grainy quality, flashy graffiti, heart and star stamps, decorative text, and short Japanese messages to capture the 'uncool-but-cute' atmosphere of old photo booths.
