Partial chords in Chromatic harmonica playing

Could you please take a moment to listen to the video above in which I played a song called “The Light Of the World"? Your feedback would be greatly appreciated.
1. I created the backing track myself using an app called MuseScore with the instruments "Voice," "Piano," and "Violin selected"
2. I incorporated a modulation sequence from Eb to E to F from verses 1 to 3.
3. In Verse 1, I used the standard single playing. In Verse 2, I added vibrato during the chorus part, and in Verse 3, I employed a "Partial chord" in the chorus part. (i.e. the same sound one octave apart).

What is your opinion on the partial chords I have tried to emulate in the choral part of verse 3?

Thank you for your time and feedback in advance.

Okay, first of all, (and this the most important part) what key harmonica are you playing? Cuz even partial chords are at best "hit or miss," and only a few actually come out right, and even those are dependent on what keyed axe you're using.
