Well, Im gonna give you my opinion based on the artists I worked with and my own productions.. based on the style your singing in and what I think you should keep or improve on, but remember its still outside opinion and you as the artist have all final say!!!
As for voice: melody line of the song is good... keep the melody line, its catchy and will make a listener interested, what I would do is work on your adlibs (they are the hardest, im still perfecting those myself), you need more of them really, by adding slight variations in th middle (subtle) and then really going off at the endd, you have a good build-up
Production: I would say with the style your going for...the beat is good, I like the beat, but you need a break at the end of every stanza.... fro example, like drop the beat, play a short variation on "tease" (for example, with a distortion on it), then drop the beat back in. This has the effect of making the beat more interesting, and its more danceable with the breaks and all...
I would like a tadd more voice tracks in the background (especially highs and lows, use extra singers if need be), and bring out the ones you have more, to get a real full choral feel going... Like you should have in soul music... I would say take micheal jackson as example, hes the king
Hope that helped in any way....
