Yeah overall this shit was banging. Great drum work, especially on the 808s and hats. I have no feedback related to the arrangement or composition. My only suggestions would be on the mix. To my ears, the 808s could be reigned in a little with some compression - I felt they were a little too boom-y at times and the upper frequencies were mixing needlessly with your other elements. Also, it felt like your upper-mids were a little muddyin general - maybe use some EQ on the specific instruments used in your sections to allow each to have its own space within the frequency spectrum. I just think this mix needs a little more dynamic range and this track would be incredible - I could hear a number of rap artists rocking over it. Overall I'm digging your shit though so I gave you a follow on SC.
