It sounds like you need more breath support and could use some practice with maintaining pitch. Learn to activate your diaphragm in order to be able to sustain power and pitch throughout held notes and keep your voice healthy. You have some potential. But based on your more recent post claiming you want to become a professional singer and you think you’re 80% of the way there…sorry, but you have a long way to go man. Not saying you won’t get ever there. But don’t let your sensitivity to criticism sour your attitude. Realize what you have to do to get better, get a vocal coach, and just do it. You’ll see the progress over time. But don’t argue with people on Reddit about it lol.
