That is pretty neat generator that generate nice islands and kingdom upon them :) Thanks for creating it :) Here are some stuff that you could add to make it your kingdom generator pops even more:
- You might want to consider for the future more of urban planning of the kingdom from inside (where is the king castle with respect to housing and the rest.
- Also, you could make some rounds connecting different kingdoms to give the feeling that these kingdoms have some trading between them.
- You can also add some layer on top as clouds using perlin noise to give life to the whole world
- change the color pallete for day and night cycles will be fun or season changes.
Overall, great entry :)
