Is it a bad idea to get n!p piercings if I don’t wear bras?

I’m a beginner and I’m trying to sing with a backing track for the first time, I know my voice isn’t very skilled but I’d like to know if this sounds alright and what I should work on! (I’m using BandLab)

Do bunnies have to have pens?

I don’t really sing in front of people and I’m not sure if I’m all that good. I’m specifically struggling with how to sing with vibrato, but I’ll take any tips or general feedback

Am I any good? (Also apologies for the low volume, I have an old phone)
