Run the same idea through both

ExampleA lighthouse keeper watching a storm roll in, dark waves crashing on the rocks below, cinematic wide shot, wind and distant thunder
ExampleLuxury commercial: a sculpted glass perfume bottle slowly rotates on wet black stone, water droplets catching a thin beam of golden light, mist drifting, macro lens, no text, no logo, deep cinematic sound design
ExamplePolished 3D animation: a small friendly robot carefully assembles a glowing glass cube on a clean pastel studio set, soft global illumination, smooth camera orbit, playful mechanical sounds
