Small simplifications in distant ornament keep it just below a flawless score.

A Gothic cathedral interior at sunset with light streaming through detailed stained glass windows, creating colored patterns on stone floors and columns. Show accurate ribbed vaulting. - Nano Banana Pro — Nano Banana Pro 5 / 10 This is the weakest overall interpretation because its interior-exterior construction dilutes the primary subject and introduces substantial spatial uncertainty. Attractive surface detail does not compensate for the compromised setting and lighting coherence.

Complex Scenes A nighttime festival with fireworks in the sky, food stalls lined up, and crowds mingling.

A nighttime festival with fireworks in the sky, food stalls lined up, and crowds mingling. - GPT Image 2.5 Flare — GPT Image 2.5 Flare 9 / 10 Ranks second, with particularly convincing night lighting and spatial organization.
