Okay, some feedback:
1stEnemyMapTheme: Cool concept but there is no progression and the percussion comes in too late. Needs a diff riff.
2ndMapThemePlayer: Again, the opening is really cool, but it sounds like it builds up to something, and then doesn't. The rhythm gets a bit repetitive, too.
Armory: Sounds like a PokeMart theme, which I guess is what you were going for.
BackStory: Reminds me of "Conversation 1" from FE4, which again, is not a bad thing. Hoping you change up the instrumentation a bit. This is also DramaticGarbage I guess.
BigBoss3: Again, the rhythm gets a bit repetitive and the first part goes on for a bit too long. The song is over a minute long, and it's highly unlikely your boss battles are going to go any more than 40 seconds, so I'd recommend making some cuts.
EarlyBoss: There's no distinct melody in the song, just a bunch of chords and sustained notes. Again, too long for an FE boss theme.
I didn't really like EnemyArrival or EnemyAttacks. EnemyArrival is more scales.
HealBot: Sounds more like a dancer song to me.
PlayerPhaseEarly: Those opening notes seem a little off... Did you put some accidentals in somewhere maybe? Again, this song builds a lot of tension, but there's no release.
Recruits: there is literally the same tune over and over and over and over and over.
I'm out of writing steam so I'll stop here. Overall your compositions aren't bad and you have great concepts but you tend to recycle the same motifs in each song leading to them sounding very repetitive. There's rarely a distinct, hummable melody in any of them so they are a bit flat. I don't think that you should throw away what you've made but there is definitely room for improvement.
