Refreshing change
It took me a few listens for the guitar sound in the first section to grow on me. A more heavy sound would have been too overpowering at the original tempo. I really liked your singing on the first section.
I liked the fact you took the song and gave it a unique sound, I really enjoyed the second section o the song, the heavier sound of the guitars and the lower vocals sounded excellent.
If I were to level any criticisms at the song as a whole it would be that the first section sounds too different from the second section in terms of production, it sounds like two completely different artists. The drums in the first section could perhaps benefit from more complex patterns but overall I really enjoyed the song, great original work.
