A Song For The Trillium Queen

First thought, the woodwinds sound a little choppy when in solo. You would definately need a better legato than the you have here. For purely classical music I would get Vienna Symphonic Library stuff. Their solo woodwinds are exceptionally well made and will not break your bank. Embertone has the best legato of the business, but they haven't released a full range of woodwinds. Their Crystal Flute is something to look into. When there's more stuff the shortcomings of the legato instrument are not noticable anymore. A good legato instrument is it's weight and more in diamonds.
 
Good use of dynamics. Now there is variation which is a must in orchestral music. Melodies and harmonies are lovely as well.
 
There are parts in the strings where one could perhaps make a bit more modulation tricks. When you have loud string chord playing and it ends give the end a little more snap to simulate the bow coming off the instrument after being played vigorously. In subtle chords you can easily just end them but forcefull playing needs a bit more faking. Just like the beginnings need a little spicatto them to make them feel like the bow go on the strings.
 
I think the percussions needs more weight. Double the timpani with and orchestral bass drum and bring the drums a bit more to the forefront. Percussions are powerful instruments when played with force.
 
Also I know you want an organic sound and feel to these, but consider doubling the bass register and octave below with a purely sine wave sub bass. It adds so much warmth to low register.
 
The ending stab is a bit weird. I'd either take out the low brass hit or add the higher register as well. Now it falls a bit flat.
