Testing GPT-Images 2.5 vs Nano Banana Pro for stop motion. Here's the prompt: "Create one square stop-motion reference photo, not a storyboard: a handmade matte-clay coral-pink cosmos flower in dark brown soil against a warm cream backdrop. Locked straight-on low camera, 70mm macro, orthographic feel. Soil fills the bottom 22%, peaking at (50%,79%); the centered stem runs from (50%,80%) to the flower center at (50%,33%). Add exactly two green leaves and a 35%-wide flower head with exactly 10 coral petals and a textured golden center. Include subtle fingerprints, soil crumbs, and a few pebbles. Use soft upper-left lighting and fixed shadows. Keep the full flower visible, with the camera and soil stationary for animation. No pot, extra plants, characters, insects, hands, text, watermark, border, or grid."
