Side‑by‑side

The same brief, three ways: raw Nano Banana Pro output, an LLM-polished prompt on the same model, and The Reelmaxing. Compare for yourself.

A note on the middle column: you'll notice the LLM-polished prompt sometimes improves the output and sometimes makes it worse. The LLM puts in more effort and aims for a more professional tone, but without an understanding of context or taste it can't reliably push a generation in the right direction. Where the polished version looks less natural, you're seeing a core limitation of current image models — short, simple prompts already produce “good enough” results, because that's largely what these models are trained on. “Good enough,” though, isn't the same as human-level design.
