So...I know you might be busy...But I'm going to give you a challenge.
But I want you to make a short song that combines the ideas and feelings from:
On the Nature of Daylight, by Max Richter,
Day One from Interstellar, by Hanz Zimmer,
and a song called Where We Used to Be from a video game called Xenoblade Chronicles 2.
You may have to do some background listening on some of these songs.
I want this song to convey the sadness of a people leaving a doomed world behind, a people that have set out for a new home. I want it to express sorrow that they've lost a world, but hope that the next one will be even better.
If you're still working on the Tien one, or are too busy for other reasons, don't worry about it. You can get to this on your own time.
