good job!
I've never played Paper mario so i don't know if your remixing it or makin an alternate battle theme. either way nice job. I heard alot of instraments but be careful when your doing this in the future because i heard some static in the backround, and im preety sure thats bad. also try turning down the volume on the loud instraments and turning up the intraments on the soft instraments to make sure every sound is heard. Good Job!!
