I'm no expert on singing, but the tone was very pleasant. I only have two things to say ( which are rather knit-picking).
First, be careful to make sure your tone is completely flat or full of vibrato. (Don't let the pitch waver.) Second, be sure to support the lower notes as well as the high notes. When I listen to a lot of female singers, their higher notes are beautiful and full, but, especially among opera singers, the tone of the lower notes sounds rather hollow. Neither of these comments are really obvious. Like I said, just knit-picky. Keep up the good work! You have a great voice.
You have a good voice. However, I noticed that when you got into your upper register, your voice pinched off. I also noticed that your vibrato was uneven. However, these things can be fixed with proper instruction. You have a certain sweetness in your voice that can and should be developed. If you wish to become an opera singer, you need to open up more, so that sweetness can flow. You're only 14, and your voice is still developing, so you definitely have time to work on your voice. I wish you the best of luck.
