Thanks @Luis Hernández- appreciate that. I didn't know Athenaton but am listening to it now - really nice, though I don't see so much similarity... Glad you introduced me to it though. (Ah, I've just come to Akhnaten and Nefertiti, and I do fort of see how you might connect them)
Yes, I think you're right about the piano having a more background role.
There is a score video - it's pretty basic though using the Cubase score. I'm only just starting to learn to score and it's coming very slowly (I only started composing last summer and have no musical training or theory, so I don't really even read music at this point....). It's near the bottom of this page - Track 13 - Prayer To The Eternal (February 2025) -
