The 3 segments appear to me after a second listen through. Here is what I get from it.
1. 1st segment -an Uproar of emotion bursting through (first 30 seconds).
2. 2nd segment -thinking more thoroughly (40 seconds to 1:30).
3. 3rd segment -compromise and resolution. (1:40 to end)
It almost doesn't need a transition but adding one with those 3 emotional effects might assist you in how to transgress from the 3 pieces.
I think adding some more strings and maybe some strong punchy percussion might adding to the song has a whole but only with the ensemble sections the solo quiet sections should stay. That's pretty much all I can think of it hope it helps.
Thank you! I was actually thinking the same about the percussion, but as a string player it's hard to progress out of my comfort zone sometimes (I'm especially intimidated by Brass). But, I do enjoy a good percussion section. Thank you for your review! It is greatly appreciated.
Please contact me if you would like to use this in a project. We can discuss the details.
