What do you think of my orchestral composition?

Watch out for your orchestration. This is perpetual issue for composers who learn to compose and orchestrate on the computer.

The form actually works. It's you have an understanding of phrasing. Though it might be nice to modulate or throw in a few more non-diatonic tones for more more harmonic interest. Gets kind of boring to here the same key for a whole piece. There were only one or two sections that dragged on too long, which is a true rarity for young composers. though it does just end midway through an idea. Ok for pop music, but very unusual and startling in classical music.

Your low flutes will never be heard in the denser sections. On the computer you can jack up the flute channel, but in real life low flute can't compete in volume against the rest of the orchestra. Do try to get real musicians to play your music as MIDI playback is really lifeless and grating, especially when you use a basic pack of sounds.

I like it,

I think it sounds nice

I closed my eyes and I could picture myself in Narnia or Middle earth
