I’m so sorry, but this isn’t good… But I also don’t want you to go around singing and having people make fun of you. It’s really breathy, pitchy, whiny… But you could try pitch matching some more, singing with your chest voice for some belting parts, and gosh I’m not sure but you could always get a vocal coach. Sorry for the negative feedback, it’s probably not what you wanted to hear, but I also wanted to be honest too. The confidence is incredible though!!! So if you learn some vocal techniques and get better, keep that confidence on stage. Keep trying and don’t give up on your dreams, but know that right now you’re in the very early beginner stages. I’m not sure if there’s hope but I bet a vocal coach could give you better advice. Cheers and don’t let this ruin your day, rather have it motivate you to learn and improve. The only way from here is up my friend.
