Critics...hmmm....
As for originality, it is a great piece.
I got your review invite and yes I got here. While I was downloading it I browsed reviews and noticed that not much was said on the actual Music. Music Theory, that is.
The intro had an inviting piano roll, just like the original. I began to anticipate a brilliant piece, for the Guitar sound(I have no idea where you got it from and I'm curious as to where) was pleasing and bassy.
But then... oh, woes... the timing was WAAY off. The synths were not playing cooperatively with the Guitar or the crashing cymbals. Plus, the sub-intro in between phrases sounded like it was recorded by a microphone to a megaphone! I abhor flaws like this in a song that is supposed to be really good according to the critics! I was led to believe that it was the ultimate and was utterly dissapointed as I see this as beating any of my newest songs by 400+ downloads...
Granted, I'm impressed to see you making such effort in such a song as this, but come on, man! Get a metronome or something and record the sounds in a more proper setting. The simplest things to fix were right under your nose, and that is why it's not very impressive.
Please consider these things in your future songs. I still have hope for you, man!
