Yes, Another Choral Arrangement of the National Anthem

I have been assigned to create(arrange) this piece, I am worried it is too dissonant and a bit too unfamiliar. I changed the instrument sounds because it is easy for me to work with any other sound than the default vocal samples. Any constructive feedback is welcome.

Actually, there are dissonances, not sure the role they have. The score would help.

It is certainly more dissonant, but not enough to disfigure it (at least to me; there are plenty of anthem purists who would disagree). I think the chromatic voice leading stuff is quite lovely, actually.
