I like the the ping pong effect in the beginning. I'm not really feeling the slayer guitar effect, and I don't really see this as a boss fight, but it's a good start. I would turn down the kick drum just a little. The melody is a good start but some of it seems a bit chaotic and could use a better flow. I like the general concept of this piece, though could use a bit of tweaking, like adding more bass synths to layer on top of the one you have already and turn it up. The kick drum kinda drowns things out. Some of it is a bit repetitive also.
It's a good start, but with some tweaking and structure modifications, you could bring out it's full potential. I like the drums in general though and a couple of the synths.
Would it be OK if I re-did this song so I can get a higher rating (under a different project)
BTW thanks for the rating
