Wow 3manonMusic, This is an incredible piece, not just composition wise but sound production wise.
The only note of criticism I have is that at 00:30 the violins come in just a tad bit loud in the mix.
Seriously though, I'm not sure what you have been up to but your musicianship has improved tremendously. The BPM automation changes sound just like how a live orchestra would speed up and slow down.
The tone and mood shifts between adventurous and brooding is a pleasant mix.
I hope to hear more of this, it's a beautiful piece.
