two kids flying a red fish-shaped kite over a paddy field in Kerala, a train passing in the background, monsoon clouds coming in

Sent with the AI image prompt generator's own instructions as the system prompt, as a free run of the tool sends them.

Graded on:

  • Nothing left out: Keeps every element of the idea: two kids, a red fish-shaped kite, a paddy field in Kerala, a train passing in the background, and monsoon clouds coming in. Nothing swapped or dropped.
  • Subject first: Opens with the subject (the two kids flying the kite), described specifically, before the setting, style and mood.
  • Light and camera: Names the lighting and the camera or composition (an angle, a lens, the framing, the depth of field), not just words like beautiful or stunning.

  1. GLM 5.3 Flash

    Failed: Graded 4.7 of 5 on average (lowest 4); but 137 words, over the 115 allowed.

    Two children, a boy and a girl around eight years old, running through a lush green paddy field in Kerala while flying a large red fish-shaped kite with a long flowing tail above them. Behind them, a colourful Indian passenger train crosses a distant raised track, and towering monsoon clouds gather in a dramatic grey-blue sky. Painted in a warm, semi-realistic illustration style with soft brushwork. Golden late-afternoon light breaks through the clouds, rim-lighting the kids and the kite, with fresh green paddies reflecting soft light. Wide landscape composition at eye level, children slightly off-centre in the foreground, train and kite balancing the frame. The mood is joyful, free and nostalgic, with a hint of approaching rain. Landscape orientation, 16:9 aspect ratio.
    
    Avoid: blur, distorted hands or extra fingers, text, watermarks, cluttered background, dull colours, cropped kite.
