Cardboard Submarine Design Generation works as-is. These are the safest ways to change it without losing the look.
Change one field
Copy a single group, rewrite it, and generate again so you can see what that field is doing.
Keep the frame, change the subject
Hold the composition and light of Cardboard Submarine Design Generation, then swap wardrobe, props or the person for a new take.
| If the result… | Why | Fix |
|---|---|---|
| The result drifts from the preview | Too many fields changed at once. | Reuse Cardboard Submarine Design Generation as-is first, then change one group — subject, light, or setting. |
| The model over-stylizes the scene | The prose prompt leaves finish and camera underspecified. | Add one camera or lighting sentence and stay on Nano Banana 2. |
