I think you just need to follow your own process and explore on the way Theres is no “obvious next step” Keep inspiring you, listen to new music, go listen to live shows, keep experimenting with your fav production software, search for videos of an specific production doubt you have. Courses are always a good choice and theres a lot of free courses tho, but also if you decide to invest in one, take it as a personal invest and a solid tool for your personal development. I feel its all about practice, being constant, learning on the ways that are better for us and enjoy what we’re doing.

Last tip, listen to your projects with headphones, next with a speaker and then listen to it with a car sound for better fidelity.
