I created a rough (terrible) sketch because I wanted to test how well Nano Banana can follow user-drawn layouts to generate a proper manhwa panel. It took me around four tries to get something almost identical to my sketch, but the result was surprisingly close.
I used both the rough sketch and the character image (my “Red Alchemist,” generated with NB Pro) with the prompt:
“I want to use the character (Red Alchemist) to make a manhwa panel using the rough sketch. Create the panel that describes the scene and the side-view perspective.”
After that, I asked it to extend the scene, which it did fairly well.
If LoRA training ever becomes available for NB Pro, it would honestly make the workflow perfect.
