Sounds like you used the same MIDI that an older version of this port used too, which is not good because it has some bad notes. Also, @0 is far more fitting for the main melody than @1, I'm not sure why you chose the other instead.
This is decent, and acceptable, but I have some major suggestions that I think would bring it up a lot more.
- I would replace that @17 with @14. It's a slap bass in the original and I think it should stay a slap bass.
- The chords throughout are an octave too low and cause the mix to be rather muddy in the low department. Pushing them up by one octave should make things sound a lot smoother overall.
- The percussion is really quiet in general, it should be loud enough that the snare kind of pops out of the mix and drives the song a bit more.
Other than that, keep in mind the in-game volume - this one was pretty loud. I lowered it for you here.
