Hmmm, some great ideas, great voice, I think the trumpet sample is a little over used.
I'm ok with the song as a whole, the chorus is fine. I'm just not used to the way it's arhythmic, inasmuch that the rhythm of the chorus lulls me into a sense of the song is getting going and I can 'key' my ears to the rails of a beat, then it wanders off into the rough, and my mind can't keep with it...Sorry
I know it's a fine piece of work, but I cannot really advise on a genre I know nothing about.
Good luck with it.
