This is a beautiful sounding track. With an orchestral suite, and especially one focused on ambience, I think this could have very easily become something generic or bland sounding, but I believe you've managed to escape that trap, making something impressionistic and cinematic reminiscent of a John Williams score or the Skyrim OST. The woodwinds and swelling strings are the standout elements to me. I don't think I can really provide any constructive feedback with regards to the theme or composing jam, but (and this is a total shot in the dark) if this is kind of composing is somewhat in your comfort zone I might encourage you to develop a stronger expression of your particular voice in a composition. Which is to say - to really make it your own. (If this seems dumb to you, feel free to ignore it.) Great piece, please write more!
