I actually liked the panning on the bass but the strings fading in and out didn't work very well i don't think. Good driving opening that gets me in to the mood of the song and doesn't let me get bored because of the new instruments constantly being introduced. The very short acoustic guitars at 0:51 and 0:56 are a little loud though. I don't think a hip-hop style rap would go well with this but it's hard to tell until you've heard it. Some singing could be nice. The melodies were a bit too static for my liking, they rose a bit but always fell back to the same base note and that got repetitive. That's probably the worst thing about the song really, the melodic and harmonic stagnancy. You tried expanding it abit with the guitar at 2:50 but even then everything else just droned on and it felt to burst out. I really did like the deeper more rhythmic bass and drum parts and there are nice riffs throughout. Good luck with future work!
