I'm sensing EBF vibes all over again.... ^_^ Or perhaps that's just me.
Right off the bat: lovely instrumentation. One thing I notice about this loop is that the sections could stand to have a bit more buildup between each other. Intro and 0:12, 0:24 and 0:25, 0:36 and 0:37. Quick fills work best with a gradual change of buildup (slight increase in loudness, slight instrument layering), but between these sections I marked out, there needs to be that EPIC TRANSITION that gets heavier and heavier and heavier until the drums come in... and then BACK TO SECTION A! I do agree with RealFaction about melodies -- and possibly countermelodies -- this might help smoothen the transitions.
0:50 has my favourite chord progression in this loop. <3 This gives me a little bit of a feel of something from Jak II. Here, because it was gradually getting louder, the transition to 1:13 was smooth.
Alright as is, but do see to it that those extra tweaks be thrown in. It's mainly got to do with 1) smoothness of transitions, 2) counter-melodies. I trust you'll see to it! ^_-
3.5/5.
