The point is you knew to use "impressionist" as a concept. ChatGPT probably wouldn't have helped you with that kernel. It's not clear whether GPT added any value at all in your use case as you just replaced "impressionist" with "{synonym of impressionist}". How would you repeat this for:

> okinawa street on a rainy night, in the style of fauvism

> okinawa street on a rainy night, in the style of constructivism

> okinawa street on a rainy night, in the style of De Stijl (Neoplasticism)

> okinawa street on a rainy night, in the style of later Expressionism, e.g. George Grosz and Otto Dix

If you weren't aware of these stylistic options at the time?
