GPT Image Prompt
Create a premium lock screen wallpaper for iPhone 17 in 9:19.5 ratio, target production canvas 1206x2622 px and required final delivery size 1206x2622 px, inspired by the uploaded image. Transform the source image into a clean, usable iOS wallpaper while preserving its core visual DNA: towering painterly storm clouds, a deep navy starfield sky, luminous blue-violet cloud ridges, magenta and pink sunset glow, soft cosmic atmosphere, hand-drawn swirling cloud texture, and a dreamy vertical upward composition.
Design the wallpaper for a Super Retina XDR OLED display with deep blacks, smooth near-black navy gradients, refined contrast, controlled highlights, rich violet and magenta accents, and no noisy dark areas. Keep the top clock, widget, status, and Dynamic Island area clean and readable by preserving a calm dark starry sky in the upper 25–30% of the canvas. Place the main visual focus in the lower-center and lower-right cloud mass, with the brightest pink glow kept below the clock zone. Keep the bottom area dramatic but not overly detailed for gesture and dock readability, and keep important cloud contours away from rounded screen edges.
Use a Space / Cosmic and Dreamy Pastel style direction with midnight navy, cobalt blue, lavender, electric violet, soft magenta, and warm coral-pink glow. Maintain a premium illustrated fantasy-sky mood with smooth gradients, clean star spacing, crisp cloud rim lighting, and elegant one-second readability. The final image should feel high-resolution, atmospheric, vivid but controlled, and actually usable as an iPhone lock screen wallpaper. No text, no logo, no watermark, no fake UI, no app icons, no phone mockup. If the generator exports a different pixel size, resize or upscale to 1206x2622 px while preserving the 9:19.5 ratio and safe-area composition.
