I love the variety throughout the whole OST as it makes each track feel fresh while at the same time all coming together to create the bigger picture. The quirky section in Owl Encounter was a really fun change of pace that I thought was brilliant! I could absolutely see the narrative playing out that you described :3
Also, your English is great! I'm not French, and English is my first language, but I am dyslexic, so I feel some of your pain, haha.
