### Full prompt
```text
Vertical comparison graphic in 2:3 portrait format, featuring two stacked wide cinematic sci-fi image panels separated and bordered by thick solid black letterbox bands.

Layout and Typography:
- Top panel: panoramic sci-fi scene in the upper third, followed by a solid black band containing the centered, tall condensed sans-serif white text "[GPT IMAGE 2]" with a soft white glow.
- Bottom panel: panoramic sci-fi scene in the middle-lower third, followed by a solid black band containing the centered, tall condensed sans-serif white text "[GPT IMAGE 2.5]" with a soft white glow.

Scene Content in Both Panels:
- Exactly one man viewed from behind, positioned center-left on a jagged, cratered gray lunar surface, wearing a white short-sleeve shirt, black vest, dark pants, and white sneakers.
- A massive Earth-like green planet dominates the right side of the cosmic sky, with a bright solar lens flare near its rim.
- Outer space background with distant stars, faint nebula dust, small moons, and scattered asteroids.
- Floating to the left of the man in each panel: two glowing, semi-translucent social media icons—a red YouTube play button and a pink-purple Instagram camera icon.

Panel Differences:
- Top panel: slightly darker and rougher digital art feel, heavy greenish color cast, lower contrast, and softer atmospheric haze.
- Bottom panel: refined and sharp photorealistic matte painting, rich deep-blue cosmic tones, crisper planetary textures, dramatic rim lighting, and high-clarity lens flare.

Style and Palette: Cinematic sci-fi digital matte painting, ultra-wide aspect ratios within panels, high dynamic range, clean presentation poster layout with [emerald green planets, blue-black space, gray lunar rocks, white typography].
