It’s very clean and bright. Capture is managed pretty well. Oddly though, much of it is more double tracked than two voices. As you’ve tweaked the arrangement it’s noticeable because the voices come in where we don’t expect them. You do it in the intro where convention suggest, if you know the original, that the voice arrives on a different chord. We hear the first chord as chord I, so we hear I, V, I, V then we expect the first notes to be in the I key, but it shocks us by actually being IV, I, IV, I, then I. We then get the double tracked really accurate melody, and suddenly we get a very quiet hum and the faster phrases that make you jump a bit. You could have panned the voices apart so we could hear each one better and realise it was a duet, not a thicker solo voice. It’s also unusual to hear two voices singing in unison like this, so you’ve certainly created something a bit different. The problem is just that all the energy is in the same place. The guitar favours the upper strings rarely E and A so it’s in the same place as the voices are. No energy at the bottom, so a bass of some kind may have helped. The guitar and vocal sync is a bit shaky in places, one going ahead. Not sure if this was intentional, but it sounded a bit strange in those places. The guitar track had a few bum notes in it. Not wrong notes, just muted or miss twanged.
it’s very clean, and the mic positions you used worked well. My comments come from years of examining, so I struggle to turn that off. Not meant as criticism as it’s really good for a beginner to all this malarkey. Most comments are minor in the recording department, most really about the arrangement, which breaks a few rules. Rules of course are meant to be broken, but only when they work. I’d love to hear more, because the voices are great and the guitar sounds way better than mine!
One thing with this song is that it is legato, in style, but you turned some words into almost staccato, and I couldn’t work out why? I’ve heard big choirs sing this and heard the directions that they must sing long and clear, but with gaps between words and clearly choirs find the blossom of snow difficult to sing long with clean gaps. Damn hard for an apparently easy song.
