I like the change from minor mode to major.
Really arresting beginning - made me sit up and listen straight away. Very suited to soundtracking, I'd've said. Nice contrast in the slower middle part - good oboe sounds and harmonies going on. I like this a lot, especially as it resolves into more major keys later on towards the end. Shades of Copland. Really, really nice work.
Congratulations on your song. It has unique qualities. Very strong melodies. Nice & catchy variations.
