The lyrics here is one verse of the song, usually to analyze a songs needs to look the whole song, not just one verse. As one verse of a song, this "song" is not a problem. However, the whole song seems merely repeating the same verse with different lyrics, There is no development, not variation, I mean, it is really boring. I imagine there must be some interludes between repeating the same stance. However, the score you provided has none. March isn't my favorite, comparing to others, but there are many great March music out there to listen to.
