I like the energy of this song. The beginning I find to be especially good. It reminds me of the OST of the DOOM Mod "Ashes 2063", it feels like it would fit really well in a post-apocalyptic setting. This might just be me but I find the "buzzer" to be a bit too agressive, I think if you tone that down a little it would be much nicer to listen to.

All in all this has some good potential. Keep up the good work.

Edit: Wow, not gonna lie that worked out way better than I thought it would xD
Sounds exactly how I imagined it. Nice one man.
