You nailed the vibes of a cold and winter track very vividly in the soundtrack, I like how well you use the instrumentation to portray emotion of each track, like the feeling of solitude and loneliness on the "Alone" track. you managed to balance the whimsical nature and the emotional sadness throughout the soundtrack
Now I know that the music style is way different in the songs but the narrative description has a similar plot to the game Celeste; from the fact that the protagonist wants to go to the frigid mountain for self discovery, to the fact that the main antagonist was actually a manifestation of the main protagonist's insecurities, literally fighting yourself. you should try looking that up and have a try, very good game.
