Length is a big issue here.
Whatever production value here is masked by the fact the song is long for the sake of being long. It doesn't maintain interest, for me.
Vocals. Autotune is cool, sure, but gets old real quick. I also sure would have loved to hear more than the one line. Like, really. If I wasn't reviewing this, I'd be out just because of how long it takes to introduce new vocal content. Near the end when you did that harmony thing, that was kind of neat.
Some of your instrumental breaks seem unmotivated musically, and just add time to this song that is already a bit too long.
I would be interested in hearing a condensed, more 'to the point' version of this song. I think you've got a solid framework up, and if you cut out some of the extraneous instrumental bits where nothing new is happening, it'd be a more dynamic, interesting track.
The broken speak n spell feel at the end was interesting. I feel the conclusion could have been a bit stronger.
Well that's what I got.
