The OP would likely prefer Disco Diffusion if they want their art to remain coarse. Modern models possess advanced spatial understanding and adhere strictly to prompts, whereas the OP is using unstructured inputs better suited for older models with CLIP or T5 encoders that lack that spatial awareness. These legacy prompting styles are incompatible with Gen3 models that utilize VLMs as text encoders. If the OP wants to explore modern architecture, they should use Flux.2 with a LoRA or perhaps a coarser model like Zit if they prefer to rely solely on text conditioning. Nano Banana Pro requires extremely long and distinctive prompting to achieve specific aesthetics. His blog post shows a lack of understanding and a lack of adaption to modern architecture which would be fine if it wasn't that dismissive.
