top-down

To explain, the first line uses the prompt top-down view, geometric shapes vibrant coloured, (grass green background:0.2) for the first 20% of steps. The general shapes/colours are established.

The second line, (city:1.3) is the prompt from 20% to 60% of steps. Transformed into a city based on those shapes.

The third line, anime, cyberpunk city is the prompt from 60% to the end. A layer of style added on top.

Outside any of that, the last line top-down is always tagged onto the end to try to keep the view stable.
