Your best one yet, you're improving. Sounds more professional and the melody/theme is nice.
The middle part is strong, the start and endings weakeast bits. Its only 4 minutes though so not much time to really lead the listener through different phases, Track structure could do with bit more variation in that regards. Percussion still lacks a little drive and personality, although appreciate the staggered beats. It would be great if there was a groove.
Holy whale balls, this sounds like an intro to an Electronic Architecture compilation. Loving it! What you can do with just an iPhone and a GarageBand... Really have no issues with the way it is, but for me this is really more of an intro track for a compilation/mix than a standalone work (but it's still great).
