This is actually pretty good. The beat's really cool and u progressed to new ones really smoothly. The only thing is you should probably layer more melodic elements to give the audio more depth. Like throw in the bass line along with the guitar towards the end or put in some sick melody at the beginning with the bassline. Maybe u wanted it to be more minimalist so didn't have too many elements going at the same time, the suggestions are just me. I could see this working in a really dark, violent, shootemup scene. Good job.
