The melodic material is nice, but I'd maybe try to use more of a question and answer form on the melody as you have a lot times where the melody gets repeated verbatim like first at 0:16 and then again exactly same at 0:24. Having the repeat be a answer to the first one would help it make the melody feel more like its developing/moving instead of just repeating, all though the repetition does kinda fit the sort of marching feel of the track as a whole
Just my subjective feels, but still, good work!
