Just by the titles, your three tracks have such a distinctive charachter and it feels obvious which Keeper belong to which world and what he carries from his past. You have that ability to create clear ambiances and give a personality to your songs. It is even more perceptible here as this is not one ost with a specific colour, but three different worlds, all coexisting in a cohesive soundtrack !
My favorite was the one for Skylark ! (Intro choir melody reminded me of Destiny 1 <3) All those bellish instruments cascading, and that explosion towards the end was so powerful, it felt heroic/powerful but heavy in carrying some tragic memories in it too, super cool composition !
Overall I feel like by focusing on fewer tracks you managed to build a great and defined ambiance for your game, with deep dives in different characters at the same time, which is super cool to hear ! It makes it very rich.
Thank you for sharing your work :)
