## The full prompt

```text
Create an original high-fashion experimental poster for the image model Nano Banana 2.1. Square composition, pure black background.
Place one large, unmistakable ripe yellow banana at the center. Show its complete curved silhouette from stem to tip, with a natural peel, subtle brown details, and realistic texture. The banana is the hero object and occupies much of the frame.
Surround it with only a few oversized transparent glass lenses and polished liquid-chrome forms. Use striking refractions and sharp reflections, but keep the banana’s entire shape easy to recognize. Dramatic studio lighting, deep blacks, bright highlights, premium 3D fashion-campaign finish.
Make the typography bold, graphic, and impossible to miss. Use solid bright-white letterforms with substantial weight, clean edges, and strong contrast against the black background. Avoid thin, delicate, outlined, or hairline fonts.
“NANO” sits across the upper area in oversized, heavy geometric capitals. Space the letters deliberately and vary their placement slightly for an editorial rhythm.
“BANANA” is the dominant typographic statement across the middle: very large, extra-bold condensed italic sans-serif, with tightly controlled spacing and a confident forward slant. Give it the impact of a luxury fashion masthead. Let it cross the composition, but position it so the banana remains visually clear; use selective layering where the banana passes in front of a small portion of the letters. Every letter must still be readable.
“2.1” appears once, large and heavy in the lower right. Align it precisely with the poster’s edges to anchor the composition.
The three elements must immediately read together as NANO BANANA 2.1. Create hierarchy through contrasting scale, weight, spacing, and alignment. Let one or two glass elements overlap small areas of the typography without obscuring any word.
Add only two small editorial labels, each appearing once: “IMAGE” and “IMAGINATION”. Set them in crisp, legible type beside a few thin white rules and precise graphic markers. No repeated small text or filler writing.
Palette: pure black, bright white, banana yellow, transparent glass, and restrained chrome. Contemporary, glossy, bold, fashion-forward, and visually striking. Render all specified text exactly. No quotation marks, extra words, logos, or watermarks.
```
