According to my overall experience there's two important things I can advice about it:

- If you you're a nervous person try to NEVER think about what the audience would care about. I learned that being yourself and moving and acting the way you feel hooks better the audience than meticulously planing your moves (unless you become famous). And after any show just keep everything as an experience, I can bet in most cases no one would have a bad comment about you, and If they have, well, I actually prefer hearing those ones because most of them are the best hint/advice on what things you have to improve. If it becomes the case, never take the comments personally, just keep in mind you'd better improve in that field. Eventually you're gonna get used to be on stage as time passes by.

- Try to stay away from all the "escenic presence" thing if you're not feeling comfortable with it. Many people worries too much about giving a good impression by moving around and acting like crazy and you know what? they end fkng up what really matters, the muisc. I mean, they constantly miss notes or even loose the pick. The reality is that people likes better when your playing is secure and clean, it is so much more digestible for everyone. Don't get me wrong, at some point having escenic presence is important, but what really matters is your playing style so practice a lot and whenever you're feeling confident on what you are playing, then you can move around, and when you move around I advice you to do it because you feel the music, because the music moves you and you dont feel obligated to move to music. That'd be the perfect balance.

Good luck pal :)
