Summer's Last Night has a really evocative intro; I love the fuzz / dist you've applied to those guitars and just how lush those chords are there. The chord progression here reminds me of The Cranberries' Dreams, which was the theme song of the show Derry Girls. I think something more could be done mixing wise / dynamics wise to really convey the magic of meeting a friend, sharing your hopes and dreams with them on that one magical summer night. Because right now, as it stands, it roughly stays at the same loudness before it cuts off for the reasons you described in the text.
Same Place, Years Later has me looking down into the waters around the pier in the intro; it has that kind of wet feel. This one is a lot more dynamic and expressive than the previous track, for the simple reason that a buildup has happened before the drums kicked in. It just stays where it does, though, without either growing louder or suddenly getting softer (to communicate something more intimate). Cues like these could actually communicate different things to us. What's happening in the reminiscing scene? I'm pretty sure that it's not just a static feeling of memories. Emotions wash over us, they come and go, and music can reflect that really well depending on the tropes we use to communicate that with others.
Good OST -- think upon more dynamics use and how that can communicate different things to the listener at different points of your songs.
Well done, and all the best this jam!
