• Camera Position: The model scored 0.44, which is below the “good” range of 0.5 to 0.75. This suggests that the model didn’t perfectly capture the intended camera position described in the prompt.
• Shot Analysis: The model scored 0.67, which falls within the “good” range. This indicates that the model was able to understand the scene and create a shot that was generally consistent with the prompt.
• Aesthetic Analysis: The model scored 0.12, which is significantly higher than the “very good” range of -0.2 to 0.1. This suggests that the generated image’s aesthetic deviated significantly from the expected aesthetic described in the prompt.

Overall, the model demonstrated a good understanding of the scene and shot composition, but struggled to achieve the desired aesthetic.
