This is pretty nice. The drums and that 808 sound perfect. You always have really nice trap drums going.
The melody/sample is cool, but I think you could take it to another level by just making the loop (for the first section) maybe double the length and then having the second half of the loop be the melody again, but a few steps up higher on the keyboard (not a whole octave). Just an idea, if you know what I'm trying to say. I hear you did do a cool breakdown in the middle of the song that was dope.
Nice beat the way it is for sure though.
