I kinda like it, but...
... it happens to have something that I regard as a critical flaw.
You see, Paper Mario music was characterised by having an array of noises. Listen to any PM 1, 2 or SPM boss track, and you'll see what I mean. You included the "ooh-ah" noise (kind of like a donkey barking?) which is the kind of thing the original had, but I don't feel it was used the right way. I much prefer the original's arrangement.
