I always love when people write ideas and melodies that are shortly out of context, then the harmony is brought in underneath and you can hear how the idea relates to the harmony. That's something you've done really well here. The really harmonically ambiguous and mysterious opening capturing the wonder you mentioned but then having it grounded and cushioned by some more comforting and warm harmony, good job!
This theme takes me back to some of the lonely mountain levels of the old Pokemon games, like the gentle snowy pass that gives you a momentary break from the relentless caves. sweet nostalgia <3
