Ahh..
You have really nice melodies, and I am in awe of the whole piece. Reverbing is excellent, and the flutes sound amazing.
The tragedy is that is sounds too busy. What I think this piece needs is some breaks! Sometimes the top notes don't flow with the mid/lower notes. =o
I think the only thing that needs work is balance. Balance creates a flowier rhythm for all the notes to shine at their right moment. Otherwise, it sounds like a jumble of notes. I think you could do better with the top melody-->it sounds nearly as if you merely pulled the perfect harmonizing notes and scattered them across the bass and mid notes in a messy way.
Because I absolutely love the beginning. At some parts like :34, though, it kinda goes from distinct to indistinct when it comes to the melody.....I don't know quite how to describe it.
Either the tempo needs slowing down, or remove a few notes to calm it down just a tad. The very bass parts are perfect, though, and they come in at their own time, as you put it, ok no wait. The very top flute is a bit loud. It doesn't seem to lower in volume much through the entire piece.
Argh, I don't want to sound like a stupid hoe. So forgive me if I do. D:
I love 1:47 as well as :20 when the top flute comes in. Try changing up the rhythm a bit so it doesn't get stale too fast, which would be horrible since the flutes have such a fresh feeling to them, especially in the intro when everything is new (kinda like this review..saying so many words to get a single point across >.<) And the overuse of the note 'A'..too many of those chords. Unless it's because this is my 10th time listening to the song and I tend to overanalyze after a while.. and ah I really love :40 and at about 1 minute. ^^
Overall, rhythm could use a little adjustment, the high flute could lower a bit, and this kinda makes me think of little kids in the forest, exploring..something to do with medieval stuff...or basically refreshing stuff. :P
I hope this was helpful! =o
