Hiya Vicki, greetings from (not so) sunny England.
So sorry to hear about your Mum. You're doing the right things to be happy anf fulfilled though, keep it up.
Mix-wise, all I can really add is that perhaps you could add some effects to your vocals at certain times? To emphasise breaks, changes and progressions in the song, that sort of thing. I don't know if you use it but BandLab is really good for that x
