The beginning of the song sounds interesting and almost as if the song would go in an entirely different direction.
The vocals are fine as they are. One thing that I feel is off is the bass groove. I feel there could have been a more active bass rhythm to carry through the song. During the "breakdown" like area, I think it could have used a solo of some kind ending with quick hi hat hits to end it.
The claps used in the latter part of the song don't sound like they belong, if you replaced the claps with maybe something else, the sound would seem smoother in my opinion. The use of the scratchy type sounds before the vocals stop for brief periods are really out of place on this one and kind of ruin the ending for those vocal lines.
Overall, not a bad piece but could be better as well.
