The backing mix is subtle and neatly done.
Vocally - you're sitting on top of the mix and there's a fair bit of sibilant noise going on.
You should, honestly, sing this song in the shower, car and while mowing the lawn for a couple of weeks and then retrack it - the lack of confidence is palpable. I can tell from what's recorded, that you could do a far better version.
The lyric does match the "classics" revisited style of the music & arrangement.
