Great job on the remix and keeping it sounding fresh and original!
As @AudibleAssassin mentioned, I would not have known it was a Zedd remix until 3:09 into it, about half your track! I really appreciate your effort and originality, it's a difficult balance to not overuse the stems but at the same time hint just enough
at the original mix. The muted vocal at 3:09 would have gone perfect in the background of the first half of the track. Maybe even chopped up/stuttered a bit.
Again, from 4:45 until the drop, you lose the connection with the original track. It's almost as if you're playing a totally separate song, mix in Spectrum for the breakdown, then mix back out. The drums sound great though, and you did a great job overall on the mixing. Lots of talent here, good luck in the competition
