Technically speaking, there's nothing wrong with your song; I really enjoyed listening to it.
However, since you asked about possible improvements or changes, I'd put "more dynamics" on the list.
I often listen to gospel music because both my sister and my niece sing in a gospel choir, and I am particularly struck by how much the dynamics and intensity change through the singing alone.
You're a really good singer, I'm 100% sure you can do that.
