Hi!
I'm a girl, completely self-taught though used to sing in choir. Haven't had any vocal coaching.
Opinions on my voice?

I'm not especially experienced in singing, but I can share the tips I know. You have a great voice, it's smooth and has a good tone. The problem is that you aren't singing with support. When you sing, make sure your lungs are full of air, even when you're singing pianissimo. Then stabilize your air by singing long steady tones on comfortable pitches. If you practice with this at different volumes and apply it to your songs then you'll definitely improve on volume and stability. (Stand farther from the mic if you're getting that distorted sound from higher volumes.) The biggest concern I had when listening is staying on the right note. You didn't always sound on pitch or in tune. Make sure you prepare for each note by looking at your music, hearing the tune and exactly what you want to sound like in your head, and then sing with certainty. Keep up your singing! Nice job.
