Same issue I've had with other pieces of yours: the drums are just not cutting it!
The lead guitar parts (for example, 1:47 onwards) are way too loud too, at some parts.
Meanwhile (even being soundfonted guitars which sometimes sound awful), you make some parts sound AMAZING. The little rhythm part just before 1:47 comes to mind really strongly. Also the build-up before the 5 minute mark is great! You got some solid drum fills in there (shame the drums are barely there, I'd love to hear them more clearly!).
Even as much as I liked the original, their mix is completely lacking in mids and it's way too gainy. You dialed it down and managed to get the really nice melodies that are hidden in there, so big props on that!
So, all in all: another stellar job, hampered by you not having some good, natural sounding headphones to mix with...
