Autumn: I think that your chord progression helps set the mood that you are trying to go for by ending on the minor chord giving a melancholy feeling. I think it’s interesting that you chose to use rising arpeggios throughout this track which is different from many of the other “Fall” tracks that use descending lines, but I think this kind of gives this a warmer feel as if this represents an early Fall day or end of Summer day injecting some optimism into the track.
Spring: You set up a grand cinematic track here and think your melodies evoke the feeling of spring well. The orchestral percussion gives a nice calm but driving undertone to your music. The high pedal synth pad glues everything together and adds to the light atmosphere. I think the electric guitar contrasts with the orchestral foundation you set up, but it does add a little energy that feels like springtime and I like that the piano takes over in the following repeat.
Winter: The falling string ostinato is reminiscent of snow falling and the upbeat tempo feels a little like shivering. The choral sounds are very well-produced and add a magical and optimistic cinematic quality to this track.
Summer: This is a very soothing track with some great chords. I am a big fan of the sound your created with the bass drum and falling bass sound indicating a new section of the song. The delay of the piano adds a cool ethereal effect to the track. This track captures the feeling of an early summer morning before the high energy day begins.
Overall: You did a great job evoking different emotions and situational imagery from each separate track. They all have a very pleasant cinematic quality to them. This is some great ambient music. Thank you for sharing!
