Steampunk Sky City

Prompt

Vertical digital illustration of a vibrant steampunk city suspended in the clouds. The lower and middle sections are filled with patchwork buildings featuring brass pipes, ornate balconies, and colorful rooftops. Hot air balloons and zeppelins drift through the scene. The upper third opens up to a swirling deep blue sky with distant stars and wispy clouds, providing a calm negative space for the lock screen clock. Warm lantern lights contrast with the cool atmospheric blue. No watermark, no logo, no signature, no text, no UI, no mobile screen, no device frames, no interface elements, no artifacts, no borders, no margins, no cropping, no cut-off parts.
