Pretty good, but...
There's hardly any noticeable variety in the loop. You pretty much wrote a 2-measure phrase and repeated it over and over again (as far as I can tell, I may be wrong).
Having said that, that 2-measure phrase is pretty good; if only you changed it a little every so often to make this loop more interesting!
Also, there's some clipping throughout the song that you might want to fix.
Overall, 6/10, 4/5.
