Personally, I would make the mix sound ( especially the piano ) a little "rounder", if that makes sense. It kinda hit my ears hard, when it first started, and continued to do so in spots. But, that said: this is a majestic version of the famous Sam Cooke song, which does it justice and then some. You, as others have said, have got the perfect voice for this. I love your interpretation, you make the song your own. Bravo.
