Whoa! That's a pretty ambitious undertaking. I've only listened to the first, er, part, movement(?), but that sounds pretty good. It picks up rather slowly, provoking the imagination, and then moves through some well orchestrated passages to a very gorgeous sounding romantic ending (over the inverted theme?). The whole sounds organic, and is well rendered. I hope your work gets the reception it deserves.
Where does the --rather gloomy-- background story come from?
