Hello!
Just finished listening to your OST.
Firstly, I'd like to lead off with my impression on your general skill with the mix. Overall, the quality of the mix is pretty stable throughout the track, so props to you there!
I could definitely see this being in a game, bringing a nostalgic summer season to life in the background.
My favorite track was July's end, I'm a sucker for the vibe you brought with that one :)
Some things I was missing in the track would include more variety in instrumentation, as well as some more melodic consistency with motifs and things of that nature. Nevertheless, the tracks stand alongside each other very well, so maybe that's not necessary after all :)
Good work!
