      "prompt": "Create a premium luxury product poster with a premium smartphone-level industrial design aesthetic, but with a more depressive, melancholic atmosphere.\n\nBACKGROUND (outside the headphone): deep matte black studio backdrop with a subtle near-black gradient and faint cold haze, minimal and high-end.\n\nMAIN OBJECT: a large over-ear headphone dominating the frame, forming an arch that frames the polar landscape inside the headband opening. The headphone is iconic smartphone orange, matte anodized aluminum + soft-touch polymer, minimal seams, refined curves.\n\nFROST / ICE (INCREASED): make the headphone visibly more ice-covered than before, while staying realistic: thicker rim frost, denser ice crystals along edges and seams, light ice rime on the earcups, subtle frozen condensation patterns, slight frosty bloom on surfaces. Avoid heavy snow piles—this is wind-driven frost/rime, not snowfall.\n\nUNDERGLOW: beneath the headphone, keep a soft warm orange underglow reflecting onto the black surface, but make it dimmer and more subdued (still premium, controlled, not neon).\n\nFRAMED LANDSCAPE (inside headphone opening): MUST match the provided reference composition and mood: dark cinematic polar scene with a dramatic central mountain peak (the middle one), surrounding snowy ridgelines, heavy storm clouds, vast frozen plain. The palette should be colder and more desaturated than before: deep slate blues, charcoal grays, muted whites, low contrast, heavy overcast.\n\nPENGUIN (BACK TURNED): a single penguin stands alone in the foreground on the ice with its back turned to the camera, looking toward the central mountain. Slightly slouched posture, small and solitary, long shadow trailing behind. Convey 'nihilist' only through body language and isolation—no props, no readable signs.\n\nAROUND THE HEADPHONE: floating musical notes and minimal annotation-like doodles (abstract marks, airy and sparse). They must remain non-legible and darker/subtler to fit the depressive mood.\n\nBRAND TEXT: 'BAGEL LABS' centered near the bottom in luxury metallic silver (foil / chrome ink look), crisp, minimal.\n\nMUSIC UI (BOTTOM STRIP): minimal music streaming app-style 'Now Playing' bar, clean and understated, showing only these words: 'music streaming app', 'Grey Static', 'Let Down'. Include simple play/pause and a progress bar icon. Keep it monochrome gray/white on black, premium and minimal.\n\nABSOLUTE RULE: No other readable text anywhere else in the image besides: 'BAGEL LABS', 'music streaming app', 'Grey Static', 'Let Down'.",
