considering its your first...
It sounds like the same beat....over....and over....and over.....and over.....
well you get the idea. im not gunna bash you fiercly because it wasnt terrible. just very repetitive. and if that was your first attempt at making a song, that wasnt too bad. i dont know if you any lyrics of any sort, but pretty much any syntax of lyrics would fit into this beat because of its simplicity (which is a good thing).
But get this: i dont even like hip hop. i hate most of the crap they put on the radio 20 times a day and then wonder why a hit became sour after a week. but you've got potential. i hope you and your music evolves into something more complex but still origional to your style. not bad for your first song.
