Anime Mirror Lake Sky Background GPT Image 2 Prompt and Rewrite Tips

Create a wide cinematic anime-style background illustration of a vast mirror-like lake under a brilliant {argument name="sky color" default="clear azure blue"} daytime sky. The horizon sits low and perfectly straight across the middle distance, with a thin chain of pale lavender and warm beige mountains stretching from left to right. The lake surface is glassy and still, reflecting the entire sky, clouds, and mountains with near-perfect symmetry, creating a tranquil infinite-space feeling. Add large fluffy cumulus cloud banks concentrated on the upper left edge and upper right side, with smaller scattered white clouds along the horizon; their reflections should appear softly in the water below. Use luminous summer sunlight, soft pastel colors, airy atmospheric perspective, delicate painterly brush texture, and a dreamy Japanese animation background aesthetic. Keep the composition open and uncluttered with no people, no buildings, no boats, and no text, emphasizing calmness, scale, and a serene fantasy travel mood. Render in a {argument name="aspect ratio" default="16:9 widescreen"} composition with crisp detail and gentle bloom.
