A very nice alternative to the other electro/power remixes of this song on NG. I'm especially intrigued by your choice of instruments in the process. Even though they wouldn't have come straightaway to my mind for this remix, they harmonise perfectly. Interludes are well woven in and the drums subtle enough to let the trumpets shine. Nice one!
If some advice is needed at all, I'd go over freestyle part again starting at 1:44 and 1) extend it just a tad and 2) change the end note of it. Everything else creates a great mashup tribute and is an absolute joy to listen to. Bravo!
