Wow
This is a very nice piece, istilling a sense of serenity in the listener. Some nice arpegios in the guitar keeping the main structure and flow of the piece going, backed up by tranquid violins. You did a nice job giving the guitar programming a realistic kind of sound in the way it's played. And considering your tender age of 15 this is very good. Though I can't help thinking it would have been better suited in the classical section.
Now for some critisism, heh.
Your instruments sounded a bit too synthetic, maybe try finding a guitarist to play for you? And some better string samples. Also I found the dynamic changes, especially in the middle of the piece a bit extreme, make them more subtle.
Maybe introduce some more instruments into the song, or have a change in the dynamic theme to make the song more intresting.
/end critisim/
Anyway, stop by the audio forum for some advice and just generally audio talk ^_^
