@2MK You've struck a chord and I'll echo what @Aleksey @Braden-Hallett and @xin-li have said.
I think your question is a little like "when will I develop my own style?" Just like with ideas for stories, how and what you draw is heavily influenced by what you've seen and what you think about. And when you draw them enough, you cannot HELP but imprint your own style or voice. You simply cannot help yourself. When you've done it "enough"--and the only way to get to that magic place of what's enough for you-is when you've done the stuff.
Write, play it out, rewrite, listen again (better yet if you have someone else listen), rewrite---and finish it. I'm working hard on taking my own advice-but its helping. Fast enough? Well..... I'm exploring this as a marathon, not a sprint, and I'll only run my first marathon at whatever pace I can run it. But so much better than sitting on the couch! (full disclosure, i do not run marathons or run at all. But I do a mean bicycyle-thing!)
Glad you're joining the crowd of asking and exploring.
