The results show that the generative AI model performed well in understanding the scene and camera position, but struggled with the aesthetic aspect. Here’s a breakdown:

• Camera Position: The model scored 0.24, which is considered below average. This suggests that the model didn’t accurately capture the intended camera position described in the prompt.
• Shot Analysis: The model scored 0.57, which is considered good. This indicates that the model was able to understand the scene described in the prompt and create a shot that aligns with it.
• Aesthetic Analysis: The model scored 0.16, which is considered very good. This means that the generated image closely matched the expected aesthetic style.

Overall, the model demonstrates a good understanding of the scene and shot composition, but needs improvement in accurately capturing the intended camera position. The aesthetic quality of the generated image is very good.
