This is an amazing piece. A good idea to incorporate in your next composition is using larger varieties of melodic rhythm. The melody is amazing but it's really repetitive. maybe adding a mini trumpet doing its own thing to go along with the main brass entourage might sound great. A big thing that I see in this piece is lots of repeating. Perhaps the idea of a bridging phrase to make the song feel much more progressive and less repetitive feeling. You can see an example of this in my most recent song https://www.newgrounds.com/audio/listen/1030261. You can see that I begin off with the primary melody for just a little bit in the beginning then I switch to a brass bridge then I revert back to the pain melody to give the song a sense of conclusion and progression. I do admit, my composition isn't perfect but there are still things others can learn from it. Enough of tooting my own horn. Going back to your horns. A good transitioning phrase would to lower the volume of the horns and have a trumpet solo and it slowly ramps up in intensity then the main chorus comes and it really makes you feel nervous like there are a bunch of guards patrolling the area looking for you. Over all, you have a very good melody and a very nice snare drum pattern. Keep up the good work!
