Prompt
A children's book illustration of a small child in a homemade cardboard space helmet sitting inside a rocket built from a stacked cardboard box with a cone of taped paper on top, in the corner of a bedroom at night, a bedside lamp casting a warm cone of light while the rest of the room falls into soft blue shadow, hand-drawn paper constellations taped to the wall behind, a toy dog buckled into the passenger seat wearing a scarf, crayon dials drawn on the inside of the box, soft gouache texture with warm and cool colour contrast, no text, no letters

How to use this prompt
The rocket has to stay unmistakably cardboard. Taped paper, a stacked box, crayon dials drawn inside — name each one, because the moment any element renders as a real spacecraft the whole idea collapses, and what is left is a sci-fi picture rather than a child's invention. Warm lamplight against blue room shadow is the standard bedtime palette and it does the emotional work of making a dark room feel safe. The toy dog buckled in with a scarf gives the scene a second character and implies a whole game already underway.
Variations to try
- Blast-off spread: the bedroom dissolving into painted stars around the same cardboard rocket
- Two-child version with one at the controls and one leaning in through a cut cardboard hatch
