This is great already! I'd be happy with this as a finished song, so it will be exciting to see a more developed version! Bags of potential here!
I know it's a demo so likely to change somewhat before it's finished but the one nit for me was the snare (I think it is a snare) that comes in about 1.30 sounds to me to not fall on the right beat...if that makes sense
Otherwise great stuff! And really thoughtful and touching lyrics
All the best
