Judges’ notes

  • AnthropicDrone always visible with tram, birds and crowds, but flat untextured buildings and a few blocked frames.
  • OpenAIThe prominent drone and busy bridge read clearly, though boxlike landmarks and overhead obstructions limit the result.
  • GooglePleasant warm roofs and visible lower-center drone, but heavily penalized for pressing into the solid bridge-tower wall at 36.2 s and a wall band at 10.9 s.

From the agent’s report

Short, verbatim quotes from the REPORT.md the agent wrote itself.

The style is intentionally low-poly and architectural rather than photorealistic.
