Comments as I am listening:
1. Your age, love that you're so young and doing this much already
2. I love the chord progression. Off the top of my head, distance-wise, assuming the first chord is Eb the second is a Gm? Could be wrong however I love that change.
3. I like the bells.
4. The vocal is not compressed enough. Way in the back. This is an emotional song, bring that in closer to people's ears.
5. The voice is not bad and it matches the genre of the song
6. I like how sparse the bass the bass is in the beginning
7. The drums sound good minus the hihats. They are too hot. Same for the crash cymbal. So now the vocal is even more "in the rear"
8. The piano sounds good.
Overall, this is a very good effort, especially considering your age. Possibly also try to write one more segment of melody, maybe a bridge or something similar.
Congrats.
