Aesthetic Analysis: The model achieved a score of 0.1, which falls within the “very good” range of -0.2 to 0.1. This indicates that the generated image closely matched the expected aesthetic described in the prompt.
Shot Analysis: The model scored 0.47, which is considered “good” as it falls between 0.5 and 0.75. This suggests that the model successfully captured the scene and composition described in the prompt.
Camera Position Analysis: The model scored 0.2, which is below the “good” range of 0.5 to 0.75. This indicates that the model struggled to accurately interpret and implement the camera position specified in the prompt.
