Hi Neil,
First of all I haven't read the other feedback so apologies if I repeat something. Also, I love the song and especially the guitar part, fab chords and they follow the vox beautifully.
For me the bass could be louder and I found the synth a little busy. Maybe a more subtle synth/strings with less embellishments, combined with something else (piano?) to keep those counter melodies in there. Minor points and totally subjective, of course 😊
