pretty cool this is
well this has that old skool gangsta vibe to it, nice police siren and the underlaying synth really compliments the mix, the beat is just aboiut right, the kick is good, and the snare/clap is okay, maybe try using a bit of variation in the snare changin from one sound to another intermittently.
that 'hey' sounded good at first, but it began to get repeptitive and then annoying as it sounds a bit cheap, maybe make them change notes with the song, give it a more musical edge, or take a few out.
The piano's nice too, just apply a longer reverb and it'll sound even better, the shot gun effect is good too, tho it is out of time with the tune, slice it up between the 'cocking' and the firing so it lands on the beginning of the beat.
anyways 8/10
4/5
