Well, congratulations, at 1:20 I went "Jesus, that's immersive". 3 minutes in, I'm still loving it. Here's the kicker, though - I'm not a fan of most trance music due to the repetitive nature of it. You seem to introduce enough variety to stave off my cringe at repetitiveness - or rather, there's no excessive repetition I can detect (or have my tastes changed?). In fact, are you sure this is really trance? OK, kidding on that last one. But seriously, I usually can't listen through an entire trance piece because the repetitiveness gets to me, and here I am, listening to silence now cause the piece has finished. My only gripe would be what sounds like cello - it sounds somewhat unnatural at a few points, either because it comes from a MIDI soundbank or it's just a limit to what you had to work with. This is mostly why I went with 4.5 and not 5 stars. Mixing acoustic and electronic is tough to begin with, however, so again, hats off to you. Keep up the good work!
