This was a neat little submission you've put together - feels pretty reminiscent of summer.
My main feedback to you is that I would've preferred the two tracks to be a bit more different, harmonically speaking. You've nicely described story you wanted to tell with this submission, but I don't quite feel like there's been any thematic or tonal changes between where the story begins and ends. It almost feels like we haven't really moved in the first place.
Maybe next time try to write some variations of your original theme to be used at a later part of the submission, or play in a more-noticeably different key. That way the listener has something familiar to latch onto, but also gives the impression that the hero has gone through some kind of change in their journey.
Thanks for sharing this - keep up the good work :)
