Track 1: This track gives me original Paper Mario vibes (one of my favorite games) and certainly encapsulates the essence of a nice walk on a Spring day. The bassoon vamp is tied together nicely with the cello and creates a feeling of a pleasant saunter with the occasional skip or two. I especially like the mode mixture arpeggio section!
Track 2: The banjo swing gives a clear feeling of a warm summer evening. I like that you kept it simple but still interesting with borrowing chords from the parallel minor key.
Track 3: I think that cello and piano sound so beautiful together and believe you made the right choice with balancing the low arpeggiated cello with chords in the higher register in the piano. This technique is very reminiscent of fall as the warm summer days start to feel a little colder. I feel like this track would work very well in a Pokemon game (D/P/P era).
Track 4: Bell tones immediately give the sensation of icicles hanging from the ceiling. I like the interjections of the flute with the glockenspiel/music box melody. Great counterpoint writing! Even thought the bassoon acts as the bass, I like how you set the harmony up well with the pizzicato strings in the upper registers.
Overall: I think your strength is your instrumentation choice and your commitment to simple, but effective melodies. I also appreciate the tasteful ambient noises as well- I felt transported to each of the 4 seasons. One suggestion I would offer for future projects is to explore using variations of dynamics in your music. There are many opportunities for swelling and backing off in the music you have here. I definitely understand the limitations of notation software-produced sounds though. Thank you for sharing your work and keep up the good work!
