Whoa, really digging the tune. I love how how epic it all sounds, in its own unique way. The drums definitely sound bigger and better in this new version. Gives it more kick.
I'm not sure how, but the transition at 0:18 actually sounds better in the original. I think it has less impact in this version when 0:19 hits. Might be because of the dying note at 0:17 sounds cut off too quickly as if it wasn't finished. This occurs in both versions, but it's more noticeable in this one. Aside from that, the song alone is really awesome. 0:19 to 0:28 is definitely favorite segment. This is going to be stuck in my head all day. :)
As for inspiration, if you're looking to extend it, ( I'm going off the original version, since that one is more 'complete') it could probably benefit by quieting down for a while and then building back up again to end on an epic note, or having an outto similar to the intro, to get that spacey feel back in. Dunno. Go crazy with it!
