겨울 모닥불 배경화면 디바이스 목업

A polished multi-device product mockup showcasing a cozy winter wallpaper across three Apple-style devices set against a light gray studio background. Each device sits inside a rounded white display card with soft drop shadows: a laptop centered at the top, a tablet at the lower left, and a smartphone at the lower right. All screens display the same Japanese crayon-anime illustration cropped to fit: five cute cartoon children and a sleeping small white dog gathered around a glowing campfire in a snowy pine forest at night under falling snow and deep navy-blue trees, illuminated by warm orange firelight. Behind the campfire stands a round-faced child in a red winter sweater, flanked by friends in winter attire. Realistic lock-screen UI overlays appear on the screens: time "[9:38]", date "[Friday, November 15]", status icons, and translucent widgets. The tablet includes an upper-left translucent weather widget displaying "[Cupertino]" and "[45°]"; the phone features three circular widgets below the time and dual bottom lock-screen icons. Clean minimalist tech mockup, thin black bezels, soft ambient lighting, sharp screen details, no brand logos or watermarks.
