You do know trap is a genre that Newgrounds offers, right? I mean the system is dinky but it at least has trap
You have good command in drum design. Every hit pops right out the mix just as it should, giving your track a lot of power and headbangableness(?). The sounds also compliment your drums very well.
I'll be honest, I was not expected 2:52. Nice surprise :) You've done a really nice amount of variation in the sound without losing the overall connection, which is great. Your transitions really help smooth all of that out.
One thing I was hoping to hear was a bit more dynamic variation. At this point pretty much every section is loud. Part of that is that you never switch the drums out where appropriate - if you make the drums softer where the song should be softer, you'd easily achieve a good level of dynamic variation, especially since those down sections have pretty overpowering drums at the moment.
Overall though pretty good work! Good luck in the compo. :)
