Cool.
I listened to it once through, and I couldn't help notice that you used the first 2 phrases of the original a fair bit, and only threw in the last couple phrases in once. I didn't get to hear the part that I love the most though, which is the other main phrase, which then goes into the chromatic-like build of epicness.
This was like the F-777's answer to Tiesto's Adagio for Strings, where he only uses the first portion of the original track. :P
As much as I love the motif, it got really repetitive really quickly. I think part of it was the fact that you really added a LOT to the original melody in terms of leading notes and doubling. That kind of stuff should be used seldomly and as a means to mix up the melody every once in a while, in my opinion. Then again, I don't make dance, but I have heard my fair share of dance.
About 2:56; it seemed really busy, almost too busy. May have been better to make a repetitive outro rather than make it like a summary of everything we just heard and then to have a couple of button notes.
Nonetheless, this was a good mix, and I'm glad you finally finished it :D
Keep up the good work.
