The most common trap with editorial illustration is producing something beautiful but pointless — indistinguishable from generic stock art. The key is the 'core metaphor' field: figure out your article's one-sentence thesis first, then translate it into an image (for example, procrastination becomes a person tied up by their own shadow). GPT Image 2 follows layout constraints like 'a limited 3–4 color palette' and 'single light source' quite accurately — feeding it too many colors just makes the result messy. Telling it 'no text in the image' matters, because AI-generated fake text is almost always misspelled and it eats into the negative space you need for a title overlay — adding the title in a design tool afterward looks much cleaner. The 16:9 negative-space instruction is there so the hero image drops straight into a blog header frame and an OG share card.
