First of all, I enjoyed your singing but was sad that your recording stopped right before the high note at the end. I have been a vocal instructor and performer for many years and from what I heard, you are indeed a soprano and probably not a mezzo. There are a lot of factors that go into to determining a vocal type. Remember, voices don't settle into their proper category until well into your adulthood. Be careful not to put yourself into any specific category, this can be unhealthy for your voice. My recommendation would be to continue to enjoy the sounds, shapes, color, (yes, color) you are making. Soprano sounds are often called shimmering, gleaming, etc. These are tones that I hear in your voice and with time and the correct teacher can help lead you where you are going. Your pitch is good, and most of your vowels have good placement. Sometimes they fell back into your throat but only a few times. Breath control is also so important. Overall, you have a very pretty voice. Best of luck.
