How to make amazing planets like Aviametals?

@Aviametal How do i use polar cap mask(i forgot) and how do i make rivers?

How do i use polar cap mask again? (i keep forgetting) and how do i make rivers?

Combination of practices, trail and error, experiments, and observation on how other people make their planets and use their noise and their modifier while opening them in Planet Studio, It will take time to get good though.

lots of my early planets from 2021-2022 also looked like they were barely modified from their original template, just with some re-coloring, but I just keep on making them and find ways to improve my skills over time to make them look more original.
