i swear to god i hear japanese girls laughing

did you put a light layer of talking or something in the beginning?

the rainy atmosphere fits like a glove
and to be honest i think it would sound bees-knees if you just spit over that track with a metronome (like no drums but on beat)
it would emphasize the words and make them stand out, just having a good verse could make the track sound more hip hop-ish especially if its an emotional piece.
otherwise i cant give you much constructive feedback that wouldnt just take you into the direction of sounding like what im used to. i like different stuff
