The voice is basically lovely but the sibilance and some "mouth noise/lipsmacks" etc. do get in the way as does some of the attack on notes.
It needs some rounding as well as addressing the above.
There're about three points, from about 1.6kHz up, where the vocal has excess energy and they vary from a plosives to strident tones.
A multi band compressor followed by some EQ carving might work, def not the other way around.
It's a wonderful song and, to do it justice, the vocal ought to be re-recorded but you know that.
Your part in the production is sympathetic, supportive and lovely.
