That sounded pretty cool, Jacob. Loads of energy, mixed up the rhythm, the lead and kept a groove going while singing at the same time.
Personally I’d say start going to open mics to get familiar, get to know the people, the regulars, and when you’ve been a few times then just have to take the plunge. It’s a new thing so accept there’ll be some nerves the first time, but only way to overcome the nerves is just to take the plunge and do it. Pick a song or two that you are as comfortable playing as you can possibly be.
Based on just this vide and my own Open Mic experience you are at an appropriate level in your play to take that plunge. You could start with the Community Open Mics: JGC Open Mic XIII / 13 - Call For Interest
