I like the 8 bit sound it actually makes you feel like back in the days where all started. However this sounds more like dupstep in a way than hip hop. I would recommend you to fill the gap between 1:35 and 2:08. Its the mistery of the song but could get some extra sounds to sound more like a suspense sound.
Overall I give you a 5/5 cause still its pretty good.
Please contact me if you would like to use this in a project. We can discuss the details.
