Goal: Create a clean promotional mockup showing a summer anime-style wallpaper displayed across three Apple-style devices, suitable for phone, tablet, and desktop wallpaper advertising.
Canvas: Square 1:1 composition on a soft light-gray studio background with rounded white display cards and subtle shadows.
Layout: Use exactly 3 device mockups arranged in a grid: 1 large laptop across the top, 1 tablet at bottom left, and 1 smartphone at bottom right. The laptop should be open and centered, the tablet should be horizontal, and the smartphone should be vertical. Each device displays the same cheerful wallpaper artwork, cropped appropriately for its screen.
Wallpaper scene: A bright Japanese suburban summer street in a nostalgic hand-drawn anime style, inspired by {argument name="anime inspiration" default="Crayon Shin-chan"}. Show a clear vivid blue sky with fluffy white clouds, strong midday sunlight, leafy green trees casting dappled shadows, quiet residential houses, tiled walls, blue metal gates, flowering shrubs, and a clean neighborhood road receding into the distance.
Characters: Include exactly 8 visible characters/mascots walking together in the street wallpaper: 1 tall father in a blue shirt and beige pants, 1 mother holding a baby, 1 baby in the mother’s arms, 1 small boy in a red shirt and yellow shorts, 1 small white dog, 1 boy in a blue top with a triangular blue hairstyle/hat shape, 1 little girl in a pink dress, and 1 round-faced boy in a green shirt. Keep them cute, simplified, expressive, and family-friendly.
Device screen details: On the laptop, show a macOS-like desktop with a thin top menu bar and a bottom dock containing exactly 17 small colorful app icons. On the tablet, show a lock-screen overlay with a small lock icon, the date text “Tuesday, July 15,” and the large time {argument name="tablet time" default="9:41"}; also include a small weather widget on the left. On the phone, show a lock-screen overlay with the date “Tuesday, July 15,” the large time {argument name="phone time" default="9:38"}, small circular widgets near the top, and flashlight/camera icons at the bottom.
Visual style: Premium Apple product presentation, crisp realistic device hardware, glossy black bezels, silver laptop body, soft ambient lighting, high-resolution wallpaper art with saturated summer colors, polished social-media-ready composition.
Text and customization: Use no headline text outside the devices. The wallpaper should feel like {argument name="season and mood" default="sunny summer vacation"}. The main sky color should be {argument name="sky color" default="bright cyan blue"}. The neighborhood should feel like {argument name="setting" default="a quiet Japanese residential street"}.
Constraints: Keep the composition uncluttered, preserve the exact count of 3 devices and 8 wallpaper characters/mascots, avoid watermarks, avoid extra captions, avoid photorealistic human faces inside the wallpaper, and keep all visible UI text small and secondary except the lock-screen times.
