Listened to The March which I assume was the one you wanted feedback, and I liked the organ and synth parts, but as a drummer, I have to say the rhythm section doesn't work that well.
You wanted this to sound like a cadence in a war, but the snare doesn't really carry it that well. As it is, it's very flat and has no dynamics to it, and every roll kind of tapers off at the end, which doesn't happen on cadences. You could try to EQ it to make it stand out more, but the rhythm still doesn't work.
Another point is to change up the rhythm a little bit. I didn't really hear any variation throughout the song, so the snare part is just the same thing over and over again. Throwing in a couple triplets here and there would help. The timpani could also use a little variation, like a roll into the next part of the song.
Personally, I would change the snare part almost entirely; I would give it a triplet rhythm on 1-2-3 and then a roll on 4, and then throughout the song I would add little fills to change it up a bit. I would also go through the entire snare tracks and give it random dynamics all over the place to make it sound more real. The timpani part is fine but I would add rolls before every section to make the new section have more impact. I would also consider adding a crash at certain points.
Other than that, everything else sounds good. I really like when the organ first comes in; I just think it would have more impact if the rhythm section built it up more instead of it randomly appearing out of nowhere.
