Epic fantasy book cover illustration. A vast open sky at dusk, dramatic and expansive. In the center, the dark silhouette of a massive dragon flying forward, wings fully outstretched. On its back rides a single rider a young woman with long blond hair streaming behind her in the wind, wearing fitted fantasy armor. The rider and dragon are rendered mostly as silhouettes, with only subtle rim light outlining their forms. From the tail of the dragon backward, both dragon and rider begin to disintegrate into ash. The solid silhouette fractures into drifting embers, gray ash, and fine particulate dust, carried away by the wind. The transformation is gradual and poetic, not violent a visual metaphor of loss, erosion, and inevitability. The ash trails behind them, dissolving into the sky. The scene is quiet and monumental, emphasizing motion forward while the past disintegrates. No visible ground, no cities, no enemies only sky, light, and ash. The mood is somber, tragic, and awe-inspiring. Painterly realism, cinematic lighting, restrained color palette, designed as a professional fantasy novel cover. --ar 2:3

史詩奇幻書籍封面插圖。一片遼闊的黃昏天空，戲劇性又寬廣。在中心，暗黑的巨大龍的剪影向前飛去，翅膀完全展開。在它的背上騎著一位年輕女性，長長的金髮在風中飛揚，穿著緊身的奇幻盔甲。騎士和龍主要呈現為剪影，只有微弱的輪廓光勾勒出他們的形狀。從龍的尾部向後，龍和騎士開始化為灰燼。堅固的剪影化為飄動的星星，灰色的灰燼和細小的塵埃，被風吹走。轉變是漸進而富有詩意的，沒有暴力，是失落、侵蝕和必然性的視覺隱喻。灰燼在他們身後拖曳，融入天空。這個場景寧靜而莊嚴，強調向前的運動，而過去正在消逝。沒有可見的地面，沒有城市，沒有敵人，只有天空、光和灰燼。氣氛陰鬱、悲劇且令人敬畏。繪畫般的現實主義，電影般的燈光，克制的色彩調色板，設計為專業的奇幻小說封面。
