Any improvement? *last post I had untuned guitar* How can I start a music career?

Hello everyone, a week ago I posted a video of me playing the guitar. Almost everyone told me to tune the guitar first, so I did :) I also got a lot of advice. Here I am again playing, a different genre though. I have two questions: 1. Did I improve, is my sound, phrasing and all that a bit better? 2. If I would want to start some kind of career/playing in jams and so on, how can I start doing that? Note: I don’t know music theory, I’m 17 and I’ve only been playing for 1.5years now, all is selflearned. Am I good enough on the guitar to play in public? For example on the street to get comfortable with a public? Thanks!
