There's something I notice about this piece which is similar to the last one: heavy use of counterpoint. The intro was different from the main body in terms of chords, but within the body, there's a lot of chord repetition going on. You do vary it around 2:00, which is great, but then there's another sequence of chords repeating... You've got an otherwise strong musicality going on, the sounds in the song are balanced out.
Things I suggest:
1) I notice that this has a bit of an A-B-C structure, given that the intro, 0:30 and 2:00 are different from each other. C could've just as well been another B. Taking the intro out, we would really have an A-A structure. Try creating a secondary theme, one that softens the volume a little, while still keeping the military feel. So for instance, keep the drums there, play them lightly instead, give more focus to an instrument which would otherwise be backing melody. Then when you come back to A, your final section, you can bring back your original melody, but with greater ferocity.
Now the piece we can draw inspiration from, for this, isn't a military one per se, but has a very strong sense of structure and dynamics. Look up "Kingdom Hearts II Final Mix Secret Ending" on YouTube and listen to the music for the cinematic in question. There's a lot to be drawn from there. Frankly, that same piece can be done with drum flourishes and a military feel as much as it was done here, but listen for the general musicality. That's what makes a piece memorable.
2) A lot of the notes don't have volume changes between them. Trust me, I can hear it, because in my earlier pieces (especially those from 2011), I made THE EXACT SAME MISTAKE. Now I know it's cumbersome to have to mouse-click the bars at the bottom of the piano roll for volume control, but even just holding your mouse down and passing through them would work. You want those notes to have the feel of someone actually *physically playing* the instrument, not a MIDI-ish feel. Think about touch-sensitive keys on electronic keyboards for instance.
The idea behind this is that when you listen to an instrument being physically played, you'd expect the volume to go up and down with some notes. As far as volume is concerned, playing an instrument is like speech. There are some syllables (or in this case, some notes) that we would emphasise, and some that we would allow to trail off. With that idea in mind, try adjusting the individual note volumes in the piano roll for this piece -- and just see how much of a change this will make!
3) Then comes the issue of reverb and mixing in general, but I will handle that in a PM or in a later episode. Once you've nailed these earlier things, we'll move on to reverb.
This was certainly a great effort, but much more can be done. Still: having heard just how much this piece can bring, and how good the music here already is, I believe in you.
