Aside from the intro running a bit long (maybe use only two measures of the drums instead of four?), I don't have any complaints about this. Your implementation of the challenge was my favorite of the week, which was almost enough to vault you to my #1 spot on its own - I took a while trying to figure out whether to give it to you or to Frank. I like that reedy instrument anchoring the melody, and the medieval 3/4 time war drum beat. The whole things works really well for me, and it builds to a rousing crescendo when the background vocals join in. Excellent work.
