暖調粉彩≈降飽和不降溫度

Push this illustration into [style: professional Lo-Fi art style]: warm, slightly muted pastel tones layered with film grain, soft focus, gentle light fade, and a vignette pulled in tight to carry the nostalgic, chill mood. Natural light wraps the character softly, warm highlights and shadows settling across skin and hair. Land the whole piece in that relaxed, nostalgic Lo-Fi comfort zone, while composition and character stay exactly as they were.

把這幅插畫推向[style: 專業Lo-Fi藝術風格]：暖調略灰的粉彩色疊加膠片顆粒、柔焦、漸弱的光線和收緊的暗角，撐起那種懷舊慵懶的氛圍。柔和的自然光包裹角色，暖色高光與陰影落在皮膚和髮絲上。整體落進Lo-Fi特有的鬆弛懷舊舒適區，構圖和角色完全不動。
