How do i make plugins? Can my phone be good enough to make one ? Just wanted to try making one or be a fully fledged plugin developer. So, where should i start and what program should i use ?

It's not always easy doing pixel arts in phones imo, especially those with small screen. But you can try with pixel editor apps like Pixel Studio or Novix.

Also, for JSON and other references/guides check this site and this.

From this point, it's up to whatever you will do
Remember, good quality plugins are always appreciated by the community!
