WOW!!...
first of all this is my opinion based on this remix:

in the original song we can differentiate some things...

1- the base of the song is different
2- the end has the same melody as the beginning
3- the second part of the original song is a bit changed (it's good that it's like that since it's a remix, not a copy)
4- the second background guitar was removed (remix, not copy)

Now let's integrate my opinion into this comment:
It's a good remix, but there's something wrong (in my opinion)... the remixed melody of the original song is missing, or a part that refers to that melody.

In short, I love it :)
