Judges’ notes

  • AnthropicDrone readable throughout but flat shading, odd black-square people, and two frames blocked by black slabs.
  • OpenAIA clear drone chase and populated bridge compensate partly for generic architecture and sparse landscaping.
  • GoogleClean procedural colors and a very readable quadcopter, but simpler blocky buildings and minor edge clipping at the bridge tower and finale.
