When you need to quickly validate illustration direction, the Nano Banana family is a go-to inspiration tool. Here are 3 AI illustration cases I ran myself—with images and copy-ready prompts.
Why Nano Banana for inspiration sketches?
Nano Banana AI and Gemini Nano Banana deliver a small illustration in minutes so you can judge color, composition, and character before heavier design work.
Case 1: Veggie dessert mashup—tomato, cauliflower, peanut, egg tart
Prompt (copy as-is):
Style: illustration, poster, tomato, full of vitality, colorful, artistic expression, special effects. Angle: side flat, cauliflower, peanut, egg tart.
Takeaway: Flat design + effect texture reads like a retro food poster; warm egg tart and peanut tones pop.
Use cases: Healthy snacks, market posters, kids packaging.
Case 2: Hug Dog—joyful run with spotted dog
Full prompt:
This is a colorful digital poster with the title "hug dog" at the top. There are two cartoon characters: a blonde woman in a pink shirt and brown boots holding a balloon, and a curly-haired man in a yellow shirt and blue trousers waving his hand. Against a white background, he is running merrily with a spotted dog.
Takeaway: Lively expressions and lots of white space for copy or logo.
Use cases: Pet charity posters, family themes, children’s books.
Case 3: Old Coffee Bean Gentleman—leaning on an open book
Full prompt:
An old coffee bean man wearing round-framed glasses was leaning comfortably against a huge open book. He is using a stirring rod as a pen to write something on the page. Beside him is a cup of his "source of inspiration" – a half‑drunk coffee. Cookies and a quill pen are scattered around. The background is pink.
Takeaway: Gemini Nano Banana felt more hand-drawn; cozy pink background and story details.
Use cases: Bookstores, coffee brand social, study decor.
Tip: keep a series visually consistent
