Good
But to be honest, the synth that comes in at :30 has moments where it sounds great and others where it really clashes with what else is going on. Reading your author comments, that may have been what you wanted, but I'm not sure it works musically.
I love the percussion and how it's strong in the back with sound sounds that overlap the other instruments. The fade out/back in with a marching sound at 3:05 was brilliant.
I would end the song at 4:00 instead of the outro, as the sudden change doesn't seem to work, unless you extended the song to continue with the synth that comes in.
Overall 5/5, 9/10. Awesome. Keep up the good work!
