Not bad at all
The beginning is pretty solid..and the drums are friggin great when they come in...Very powerfull.. this would be great for an action game like madness or another walk around and kill things game. Although i think around 1:14 I kind of lost sight where it was going and i felt like there should have been a buildup to something harder along with a melody.... This has potential to be a solid ten if you add a lead line after a buildup and change around the drums a little more cause towards the end it doesn't sound like a beat but more of a series of pulses.. ,also i think you should make it so it sounds like a solid loop like near the end do another buildup into the beginning of the song.
I definitely like the use of rhythmic harmonies it works really well...
4/5 for potential
7/10
