These are really cool! You said that the best feedback for you would be to see what you're aiming at, (0:39 in Under the Mountains Dark and Tall). I like this part a lot! Something that I personally don't like is that the song develops very slowly, and to me never becomes "warlike". Its more a sad slow song, but from what I can tell its not what you envisioned. I think the main reason I interpret it like this is because it sounds like the funeral march, with the background instrument on every beat following the chord, and the vocals following a similar pattern to the funeral march, of starting on the 4th beat, long note on the first, more melody on the 4th and then another long note on the next first. Again this works really well in the beginning to build tension in my opinion, but it becomes very sad over extended period of time.
At 1:55 you change it up, and make it more "warlike", but then it goes away again at 2:00. In my opinion to make a song "warlike" you need a melody that is proud, you need an anthem that people can yell when running into battle.
A dumb example is diggy diggy hole. Its not really what you are aiming for, as yours is a lot more vocals based, and very drum light, and also not as happy and slower (yeah I guess it really isnt what you are aiming for), but the chorus is proud (and its about dwarves).
Small nitpick about the drums, making it louder is good, but it might have been better to change the pattern, and have more hits, rather than one louder one.
Either way it still sounds really nice, Im just nitpicking, and if the effect you mean by "warlike" is sad (like aftermath of war) you can disregard most of what I said. Really cool entry!!
