Preety good
I'm not a big fan of the melodic deathcore style I can see you're looking for with this song, but hey, it's still preety good. The drumming isn't 100% together and the guitar intro was a litle messy, but other then that real good job.
Also, MexicanXmosheR, Dethklok doesn't have an "a" in their name and "the one [song] about the Troll" is called "Awaken". Lastly, true metalheads don't use the term "dawg" on a casual basis, thank you very much.
Great job on the song, SlothClock.
