Examples
Create a minimalist black-and-white typographic illustration of the scene riding a bicycle using only the letters in the phrase '{{appName}} Nano Banana API'. Each letter should be creatively shaped or positioned to form the rider, the bicycle, and a sense of motion.tes with the text.
Create a character figure of Iron Man. Behind it, place a box with the character’s image printed on it, and a computer showing the Blender modeling process on its screen. In front of the box, add a round plastic base with the character figure standing on it. Set the scene indoors if possible.
A single comic book panel in a gritty, noir art style with high-contrast black and white inks. In the foreground, a detective in a trench coat stands under a flickering streetlamp, rain soaking his shoulders. In the background, the neon sign of a desolate bar reflects in a puddle. A caption box at the top reads "The city was a tough place to keep secrets." The lighting is harsh, creating a dramatic, somber mood. Landscape.
