This is a nice one, but the audio is a bit lo-fi (dunno if you were looking for that, it seems to be getting popular lately). Also, this synth-thing that you put: more often then not, it doesn't match the rest very well. And consider making it loopable if it is a beat for hip-hop or rap, when you make something like this you should either try to make it long enough to rap oer it or make it loopable if it is short.
