I don't see why this piece has so little...

I'm giving this piece a review specifically because noone else has.
From all that I can hear you are currently using the Roland Edirol orchestra package, which I myself have quite some experience with.
There are a few key details I like, and another few I dislike about this musical piece in it's entirety.
To bring out the positive, there's alot of diversity and you are not bound by the time signature due to the lack of percussionate work in the song, until the end.
I'll assume it's in 3/4 or some timesignature much like it, which is very usual in this sort of music (ie: Pirates of the carribean).
The diversity between the themes are always a positive side, especially since you didn't stray too much from the initial feeling of the song.
I like this song, but the way it is presented is not among my favorites.
The production-level of the song isn't as high as I would like - but this is mostly because of the sample-package you are using.
The spiccato strings doesn't really sound like strings, because of the breathy tone in them - in addition they sound very muddy sound-wise.
In addition, the percussion was a tad too simplistic for my taste, but at the end it did conjure quite the imagery, which must be considered a positive thing.
From here, if I were you I'd start downloading a ton of free drum and percussion samples, and start messing around with them. The edirol percussion kit is rather bad, and even though it's simple to use in most settings - you shouldn't be defined by the samples you use, but by the talent you have.
As such, I suggest you try to broaden your sample libraries so that you remove some of the initial limits set by only using one sample package.
Please, I mean no offense by anything written here -- I am merely attempting to help steer you in the direction you yourself wish to take.
