Overall, I think this is an a bit above average arrangement. It started off minimalistic- a good starting approach, leaves plenty of room to build up too. The theme sounds good, chords seem right. Nice use of percussion.
My complaints however, are that it stays minimalstic nearly the entire peice, which is quite frankly pretty boring. It never builds up to where it needs to go in my opinion. I think a good example of building up would be a loud as hell, huge, thick, chordal entrance with brass playing the melody at a decently fast tempo with a good catchy countermelody. Also, some of the samples, like the orchestra hit sound kind of fake.
But other then that, good job. It's overall a good peice.
I give it a 6.99/10 (ALMOUST a 7.)
