Great work.
I enjoyed this one. Easily the best entry in the orchestral MAC contest so far. Of course, NG loves its big, obvious & overblown epic tracks more than thoughtful, slowly-developing and more challenging music, but at least you'll have my love if not the contest's. :)
Some thoughts - the orchestration seems a little flat. Perhaps this is just a case of difficulty making an accurately colourful mockup with virtual instruments, or the limitations of the smaller and fairly homogenous-sounding ensemble you've chosen, but the overall texture, while suitable for the melodic/motivic material, could use some variation - mainly if used as an entry for a contest that will highlight the idiomatic nature of ALL orchestral music.
The musical ideas themselves are obviously headed in an original direction, but sometimes fade into atmospherics in terms of interest, rather than always being fully engaging material (note: engaging doesn't always mean FAST/EPIC/STUPID/ETC to an experienced listener, so no need to sacrifice the mood you're aiming at). This is something I'm sure is just a matter of improving your craft over time, so I can't really give any advice on it.
Anyway as I said, I enjoyed it and listened fully through, keep up the good work!
I think I'll put something together for this contest too... see you around!
