I give this a personal 6.5/10; I tried to match the artist's style of phrasing/performance and really emote. Slow songs are definitely great practice for this type of attention to phrasing (in fact I recall Phil and Marnell discussing this in a video lol).

My version:

If I'm To Die Before You
Originally performed by Keaton Henson

I:
If I’m to die before I reach you
Please know I’m meant to love you till I did
If I’m to slip beneath a train meant to take me
Know that I believe that it was worth it
Tell my friends goodbye
Tell my almost wife
That I loved her and left her too soon

[Chorus]
Oh I hope to be holding you soon
Who knows what happens if I leave my room
Oh I’m scared that you’ll know what to do...
If I’m to die before you

II:
If I’m to die before I hold you
Know my arms were the worst off for it
If I’m set upon dried
From my room as I write
You won't be my last
Thought before I quit
Give my family love
I would watch from above
But I fear there is nothing but sleep

[Chorus - Variation]
Oh I hope to be seeing you soon
Don’t know what's out there
More fear I assume
Oh I’m scared that you’ll know what to do...
If I’m to die before you

III:
And if I’m to die before we spend a soft day
Know my final thoughts will be of regret
If I'm to drown in the deep sea that parts us
I once lived and loved, don’t forget
Give my paintings to Alice
Tell all my good friends
That I didn’t dare earn their respect

[Chorus]
Oh I hope to be seeing you soon
I don’t know what happens if I leave my room
Oh I’m scared that you’ll know what to do

If I'm to die before you
If I'm to die before you
