Beat 3 is perfect for a freestyle. Although a bit mono-tone since there's not a lot of mix-up. Still got my vote though!
Beat 1 got some avant-garde going on, i like the orginality!
Beat 2 is dope, it needs more power though. The sounds aren't really popping, which is exactly what it needs!
Props to all 3 producers, this battle was fun to listen to!
