If you are just starting out your artistic journey, you are blessed with freedom. You can choose to do whatever you want. You get to build your skills, your style, and your portfolio along with your audience.
A body of work needs some consistency over time, for both the artist and the audience's sake. A singer builds an audience because they stay loyal to a genre and style.
All artists should evolve. But when you've established an audience, change is hard. When a band releases a new album that doesn't sound like them, fans complain. It doesn't matter if it's good or not, what matters is that it wasn't what they were expecting.
Take advantage of your current freedom, don't be afraid of experimenting and sharing the results. Eventually, you'll settle on a style that clicks with you and an audience.
