Going further, one thing you can do is give Gemini 2.5 a system prompt like the following:

And then pass Gemini 2.5's output directly to Nano-Banana. Doing this yields very high-quality images. This is also good for style transfer and image combination. For example, if you then give Gemini 2.5 a user prompt that looks something like this:

You can get aesthetic consistently-styled images, like these:
