Great voice.
Horn samples need to be replaced. They are not even good in a cheesy way. I think samplitude is still offering a free sample set with their free sample player ( and it includes brass ).
The guitar on the first track sounds too sterile, lifeless and looped. Is it a sample ? Can you get someone to play it for at least 8 bars then chop it up ? Also, it would benefit from some stereo reverb.
The grainy sounding recording, is that due to a heavy handed application of iZotopes Free plugin Vinyl ?
