Great use of Strings.
Oh those Strings are gorgeous. Spectacular execution of emotion :)
The Flutes are slightly too loud and sharp, I think they should have been made slightly quieter, in my mind I imagine that they should be close, yet distant, much like the way that when it is dawn, the birds in the trees seem to be everywhere at once yet nowhere to be seen.
In truth, I would say that the Strings part is worth a 10, the rest of the piece varies in value, the beginning I would say is an 8. The way you introduce instruments is also very well done.
Fiddle around with the volumes of each track, this piece would benefit from a bit of balancing.
Second of all, I feel that there could have been a bit more musical variety, vary the flavours a bit more i.e lead the chord progression down some interesting side paths, add a bit of drama here and there, to provide emotional contrast. You sort of did this at around 2:00 to 2:16.
This piece is very grand and elegant - it sounds to me like it would be a great piece to be played at a 'Fairytale' wedding, for instance.
Also the bass notes at the ending should be a bit more prominent, to provide that 'This is the ultimate conclusion' feeling, a grand summary of the music. A good climax in music rounds up every part of the music that has come before it, in some way, it brings together all the melodies/harmonies/flavours etc as one. I am sure you know this already though, and I am probably just reminding you here ^_^
Well done :)
