i must say i was relatively excited having seen the source (been playing that game like crazy) and this is definitely one of my favorite songs in the game
now, seeing as how this was your first remix, i'm gonna be brutally honest and say that this is kind of a production nightmare (youtube's poop quality probably isn't helping - use tindeck ). that synth is way too loud and dominates the mix most of the time. the long release/reverb also causes the notes to bleed together and generally crowds up the soundscape - esp. the chorus sections at :38 and 1:38; the drums and rhythm guitar are practically inaudible during those sections. it's simply unbalanced; some elements are way overexposed, and others are hiding in the background. essentially every sound should have it's place in the sound field, without stepping on the toes of anything else.
as far as arrangement goes, it's more of a cover, and a fairly simplified cover at that, but kudos for picking this awesome song.
anyway, i don't mean to be harsh, but since you're looking for honest feedback i figured i'd go ahead and dig in. judging by the other mixes you've posted on the board (i'll get to those soon enough - lavender btw has some great moments), you've certainly improved quite a bit since this, so don't take it to heart.
hope this helps
