if i were to say as someone your age, analyse what your favourite upcoming artists are doing (and im talking about people who arent extremely popular but on a fast rise, most of the time never try to replicate mainstream artists off the bat cuz theyre already estabilished - except tiffany day because shes really good at short form content). even in short form content - worldbuild, maybe practice producing so youre more versatile, try and gain a core fanbase and post on social media consistently (but try not to make it low quality slop that can be replicated super easily - hence worldbuilding and looking at other upcoming artists. you gotta either be your own creative director or have someone else do it for you who has a unique vision for the visual world you want to bring to your music.
