Nano banana limit test

What a good result
Promot :
A hyper-realistic macro close-up of a peeling banana made entirely of translucent iridescent crystal. Inside the banana, instead of fruit, there is a miniature, highly detailed steampunk city with moving gold gears and tiny steam clouds. A small neon sign floating in the center of the city explicitly reads 'NANO'. The object is resting on a wet obsidian surface reflecting the scene. Cinematic volumetric lighting, subsurface scattering, 8k resolution, ray tracing, sharp focus
