Mega Man Zero is a criminally underrated series, with music that matches the best of the Megaman series. It kind of makes me wonder why there isn't more awesome arrangements of it... perhaps people just didn't get too far in the games of the series? They were pretty tough, after all...
As far as the arrangement goes, it's pretty cool. Making the track into something of a rock arrangement fits well with the source, and the synths used in this compliment the rock elements of this track well. The rhythm guitar and drum work is pretty solid, as far as performance is concerned, so nice work on that.
The lead, while serviceable, doesn't sound like a clean performance. The timing is often sloppy (like the grace notes at 1:28 & 1:35), and the notes sound like they have an unintentional degree of separation between the notes when the notes get really high. Tighten up those entrances and rhythms, and connect your notes better in the higher end. One last element is the doubling involved later in the track at 2:06 sounds strange - the lower guitar that doubles it hits on a slight delay. It sounds like the intent was to create an echo, but it instead sounds like it's just missing a beat since it's an octave lower. Line your doubling up better.
The mixing of this is a larger overall concern for this arrangement - the lead pierces, and the middle elements (rhythm guitar, bass, synth) sound like soup behind it. Overall, the varying elements need to be balanced better - hold back the lead a bit, separate the middle elements so they're more distinct and bring out the kick and snare of the drums better.
I think this has some solid potential, but the lead performance and mixing hold back. I hope to hear some improvements on it, because the arrangement is slick, and the transformation to rock is awesome.
