I know the low rating feeling :( But here are a couple of things that may help improve those ratings.
First off, I don't think that this is a heavy metal song so try labeling your songs correctly, this may be closer to a hip hop loop.
Second, the song needs to be mastered so that it competes volume wise with other tracks on this site, so at the very least put a limiter on you 2bus.
Lastly, it is boring, there is no change in the song at all if you are going to use loops like this it is always good to add variance and make it a longer so that it is a full song.
Hopeful this helps! But you have a good start.
I picked the "Heavy metal" on purpose this time.
It took 2 minuts to make & I do not expect big surprising ratings.
