The voice is impressive but it's also the type of voice that could use some more digital work.
Add some more reverb (especially since this song is very translucent anyways)
In some cases it would have definitly appreciated some autotune that digitalizes the voice a bit
But most of all the voice needs more dual tracking in each ear to invoke interest.
The beats and instrumental itself is moderate and well done but not mastered very well.
it's clean and simple yes but not engaging or ear(eye) catching.
For some people they will love this song more than I do as I tend to like harder pressed songs that blare. So take my words to heart and keep making music!!!
