I'm no expert with production, so I can't be too helpful, but, in my opinion, you need to build the sound more so it gets stronger for the second verse. And again for the second chorus. I suggest hitting the first half of the second chorus much harder and maybe back off again gradually for the second half and then go all the way to minimal for the final "This is love", maybe even repeating it.
The melody is beautiful and suits the words wonderfully. When I read the lyric alone, it didn't feel really strong to me but, in the context of the melody, I like it much better.
I get the feeling you're holding back with your vocal in an attempt to set the mood. As a result, your vocal is on the weak side. I think it's possible to sing with more intensity without losing the vulnerable sound by using more breath support while singing at the same low volume.
In the first verse, I have a nit with your pronunciation of "surround you". You've run them together and made them sound mushy; I'd like to hear them clearly enunciated, especially in this song.
In this line:
We stand in the middle. Know that you're the onethe word "know" is on a weak beat followed by the word "that" on the strong beat. The word "know" is much more important than the word "that", therefore should not be overshadowed by it this way. There is more than one way to fix this--you could try singing "I know you're the one" which would do it easily. You could also sing "Know that you are the one", keeping both "know" and "that" BEFORE the strong beat and making "you" the important word. But I believe it's very important to showcase the important words, not the unimportant words.
At the risk of being repetitious, when you get to the second verse, I'd like to hear your voice building, along with the instrumentation, gradually throughout the second verse and first half of second chorus.
This is all based on my opinions, of course, so use anything that speaks to you and discard the rest. I'm especially not qualified to make production recommendations, although you can see I did so, anyway.
I do hope you'll consider working on the prosody of the "Know that you're the one" line, though.
Beautiful work, very heartfelt interpretation.
