Go go penguin power!
Well the instruments sound realistic. That's a fantastic thing, as many synth programs cannot get the brassy sound correct, nor can they properly get the trumpet's correctly. So thumbs up for that, but speaking as a trumpet player myself, trumpets shine when at the forefront of the band blasting their hearts out. They are meant for impact, not just soft jabs. The flute makes up for the trumpet's meek toots with their very powerful entrance. I just wish that the trumpets could shine in their respects, snares are always nice in a march as well. The good in this song far out weighs the bad, great song 9/10.
