It's a pretty good remix. :3
At around 1:00, the violin is really like.
The only things I want to pick out is that the metal percussions are a bit too loud. I think it's better to position them just behind the kicks, because it just becomes noise when it competes with the other instruments.
1:53 could be a bit better though. If you added a little more intense instruments at that part, it would be epic.
Also I noted some weird note velocity changes, it would be soft one moment and then loud the next.
But since it's a speed remix, some mistakes are acceptable--and this is a good mix. :3
Hope to see more from you soon. XD
