This song plays during the Fantasy Knight transformation in Ape Escape 3. It's a repetitive, yet catchy tune. It's fairly short, so it's probably not a good idea to use it in long levels. I'd say it's best suited for an overworld, bonus room, or cut scene.
I think original's panning of the mix with your own percussion choice of pannings would have been more balanced. The bass and string's panning would sound better flipped, while the chords panned opposite to what you have right now. You did an amazing job as always with SMW's samples. I take back what I said about the cymbal after hearing the original. It'd be nice to hear a full sampled version as this sounds pretty spot on notation wise!
