蓝天白云晴空万里海报壁纸白云缱绻

Blue sky with white clouds, close-up, realistic photography, bright light, no shadows on the ground, no sun in front of the camera, clear cloud outline, no black ink, no distortion or broken edges, no sharp corners, no reflection in water, no water below the horizon, no reflections from objects. The overall effect is clean and refreshing, with a simple background. It's like looking at an endless blue sea, full of tranquility and serenity, in the style of the artist. --s 250 --v 5.2 --ar 16:9
