Wow, sounds like The Legend Of Zelda ! ^^
The melodies are perfect, I mean almost flawless ! They fit well together and are complex and creatives ! The only problem is that they are not really memorable, I think because it's not repetitive at all. I mean it can be a good thing, but if you "harass" the listener with a memorable melody, he will remember this melody and your track will have a better personality !
The instruments were simply awesome ! One of the best mix combination I've ever heard ! They were well used especially at 1:05 (the horns which add drama to the melodies) and from 2:29 until the end, which was simply epic !
Well, as I said before, the track looses personality due to not-so-memorable melodies ! But it's an uncommon style which is pleasant to listen to !
Melodies : 1,5/2
Instruments : 2/2
Personality : 0,5/1
It's clearly one of the best piece I've ever reviewed : well done ! =3
