What do you think of my singing?

You're great! You sound a little airy. If you try breathing from the bottom of your stomach rather than your chest, you'll get a clearer sound. If you catch your shoulders moving as you breathe, you know you're breathing the wrong way. But if your stomach puffs out when you breathe, that's how you know you're breathing correctly. Plus you'll be able to sing longer! You sound awesome though. Love the song choice :) Keep singing!!
