I would turn down the snare a little, and I would try and make the instrumental a little more fuller, maybe add some quiet lower strings or you could throw some bass guitar in there, nothing extreme, just some suggestions, just play around with it. Im not a rapper or a lyricist so I cant judge the vocal track to well maybe record not so close to the mic, sometime the vocals get slightly distorted but it could just be your mic but overall it sounds likes its coming together nicely. keep it up
