The sound of this is really interesting. I recognize what sounds like an inspiration from another song, during the beginning, as that sound is extremely familiar to me. But the song has a very gamey sounding feel to it, overall, however, different, singular parts are well equipped for almost any multi-medium project out there. I like the compliment of the clear sounding sounds with much more 'fuzzy' sounds.
It has a feel very similar to a chill, jazzy form of the game Phantasy Star Online, if you've heard of it, albeit a very different style from what most of the soundtrack focuses on.
As far as criticism goes. I'm not sure what to give you. The song is very interconnected, and it seems to follow a very well put together template designed to bring the best out of the sounds and sequences of sound within the piece. See? I sincerely cannot criticize this piece, though I am by no means a person suited for music criticisms, which is likely why I am incapable of doing so. Still, very well done, this is one of my favorites.
