Nano Banana Pro Test: Ultra-Wide-Angle Photograph from the Surface of a Tiny Habitable Planetoid

Decided to test this with Nano Banana Pro. Not bad :) 'Prompt: A ultra-wide-angle photograph from the surface of a tiny habitable planetoid only about 500 meters in diameter covered in a dense Tokyo-like city. The curvature is so extreme that buildings on the "horizon" are visibly perpendicular to the viewer and the city loops entirely overhead filling the sky with inverted skyscrapers. The sun is visible as a star behind the overhead city. The ultimate fish-eye reality.'
