Basic sounding piano...
The melodies and harmonies you used on the piano werent bad, however, the basic sounds you used (FL Keys, Slayer, FPC) really took off from the song. If you updated some of things, this would sound a lot better.
7/10 and 4/5.
I Liked it, but that guitar hurt my ears despite the fact that it went so well with the song.
It has its ups and downs, but I really like the part where the guitar first comes in. The percussion work is great, and it sounds like you had some fun. :) Nice work!
