The Choral Padwork has too much low end in it (I'm guessing)... if you'd do some EQ work or some filtering, I imagine your mix will clean up a lot.
The Guitar lead line is cool... and I like the multiple Melodic riffs you start bouncing off of each other around the 1:30 mark. Imo, the Horn sounding lead would sound cooler if you did some kind of Filter Mod on it.
Cool drum changeup at the 2:20 mark.
I wouldn't necessarily "take anything out"... but overall:
1. Intro into the drums is a lil too abrupt imo.
2. Outro is non existent.
3. Mixdown in regard to Perc needs work because the drums are too distant in the mix.
