Ooooo FL Slayer, Dope! This piece was pretty kickass, I will say it does ride a bit on the louder side and can be a bit harsh on on the ears. I noticed it mostly at the :50ish mark. I love the riffs at the 1:24 mark! The synth you used there is nice! To bring back what I said about dynamics, you could actually play around with them a little more! I saw little bits and pieces of it but I think there could be even more places of lower volume so the bigger parts just slap ya in the face even more!
Great piece! Enjoyed the listen and your synth choices!

Good song :)
