Hoist The Colors

This arrangement took about 2 days to make, so hopefully, it sounds good(even though it might not). I did this arrangement because I want to try and get my chorus teacher to let us sing it at one of our concerts. And yes, our chorus has girls and guys that can go this high and low.
I had to first write the solo(melody) by itself in order to get a foundation. Then I started adding basic harmonies. Once I got basic harmonies, I started to add some dissonance in order to give it a little more eerie feel. Once I did that, I started adding the grace notes and the very, very high soprano notes. After all of that, I added the high tenor part that is supposed to be belted out for everyone to hear by 1 or 2 guys.
I hope that you like it. Please give me some feedback. This is the hardest thing that I've ever done.
