Minimal drums (side-stick snare, gentle kick) and a supportive, root-note focused bassline create a sparse, emotional foundation.; Instruments: Fingerpicked acoustic guitar (arpeggios), warm grand piano (chords/melodies), clean electric bass (low-end support), minimal drum kit (soft touch), lush orchestral string section (swelling pads for emotional lift).; Vocals: Male tenor, intimate and breathy with a slightly raspy timbre. Mix of chest voice and gentle falsetto for emotional emphasis. Light reverb and natural compression.; Mood: Melancholic, introspective, heartfelt, vulnerable.; Production: Polished, spacious mix. Vocals are upfront and centered. Wide stereo field, especially with strings. Hall reverb creates an emotional, expansive soundscape.; Highlight: the intimate and breathy vocal delivery, transitioning to a gentle falsetto.",

    "scene_description": "深蓝色黄昏海湾，孤立礁石伫立于退潮后的浅滩，礁石表面覆有苔藓与贝壳，远处一道模糊身影站在潮水线边缘，天空泛着冷橙与暗紫交织的余晖，整体氛围孤寂而克制",
    "cover_prompt": "A lone dark basalt reef standing in a shallow tidal flat at dusk, the sea water has just receded leaving wet sand reflecting a cold orange and deep violet sky. A blurred solitary figure stands far at the waterline, back to viewer. Moss and barnacles texture the reef. Cinematic widescreen composition, melancholic and restrained mood, muted color palette of navy blue, slate grey, burnt orange, no text, no people in foreground, photorealistic painting style, soft volumetric light, album cover 2048x2048.",
    "selection_reason": "歌词以海湾礁石为核心意象，潮水涨落象征情感的进退与拒绝靠近，情绪风景模板能将这种克制的孤独感直接视觉化，冷调暮色与孤岛礁石的构图强化专辑的内敛忧伤气质"
